Introduction to Research Methods

Introduction to Research Methods

Research is like solving a puzzle: you need a systematic plan to uncover reliable answers. This plan is what we call scientific research methods, structured approaches that guide how information is collected, analysed, and interpreted (Bazen, Barg and Takeshita, 2021). In academic writing, this is often referred to as the research methodology, and it ensures that the findings of a study are valid and trustworthy.

Broadly, there are different types of research methods, each suited to answering particular kinds of questions. For example, some focus on numbers and measurements, while others explore stories, meanings, and lived experiences. Throughout this guide, we’ll explain the main approaches with clear examples of research methods, from interviews and focus groups to surveys, experiments, and data analysis techniques,so you can see not only what each method is, but also when to use it.

Research can be approached in many ways, qualitative, quantitative, or mixed, and students often struggle to decide which path fits their dissertation or thesis. To make this easier, let's first understand the types of research methods.

1. Qualitative methods – deal with words, experiences, and meanings. They answer “why” and “how.”

   Example: Interviewing patients to understand their feelings about hospital care.

2. Quantitative methods – deal with numbers, measurements, and statistics. They answer “how many,” “how much,” or “how often.”

   Example: Conducting a survey to count how many patients were satisfied with hospital care.

Think of research data like ingredients in cooking. Sometimes you need fresh ingredients you collect yourself, talking to people, observing behaviors, or running surveys. This is primary research data; gathered firsthand by you, the researcher. Other times, you can use pantry staples, such as existing documents, datasets, or past research already available. This is secondary research data, meaning it's information collected by others. Both can create a 'delicious' research outcome, but the process and flavor of insights differ.

• Qualitative Primary – You talk to people, observe them, or record their stories yourself.

• Qualitative Secondary – You analyze diaries, documents, or past interviews already available.

• Quantitative Primary – You collect numbers firsthand through surveys, experiments, or tests.

• Quantitative Secondary – You use statistics or datasets already published by governments, companies, or researchers.

Think of it like cooking: sometimes you buy fresh ingredients and cook from scratch (primary data), and sometimes you reheat leftovers or use ready-made items (secondary data). Both give you food, but the process and freshness are different.

In this guide, our focus will be on qualitative research methods, explaining them in simple terms, showing when to use them, and giving easy examples. However, if your dissertation demands a more statistical or numerical approach, you can refer to our separate blog on quantitative research methods for a detailed guide.

QUALITATIVE RESEARCH METHODS

Primary Qualitative Data Collection Methods

I. What is an Interview?

An interview in research is a one-to-one conversation between the researcher and a participant, making it one of the most common qualitative research methods for collecting in-depth data (Jamshed, 2014). The aim is to explore the participant’s personal views, experiences, or stories in depth. Unlike surveys that give short answers or numbers, interviews allow you to dig deeper, ask follow-up questions, and capture rich detail.

Interviews come in different forms

• Structured Interview – The researcher asks a fixed set of questions in the same order for every participant. Best for collecting comparable data across a large group.

• Semi-Structured Interview – The researcher prepares guiding questions but allows flexibility. This is the most common type in dissertations because it balances structure with open discussion.

• Unstructured (In-Depth) Interview – More like a free-flowing conversation. The researcher has a general topic but lets the participant lead. Best for exploring new or sensitive areas where stories matter more than standardised answers.

• Online Interviews – Conducted on Zoom, Teams, or similar platforms. Useful when participants are spread out or when face-to-face meetings aren’t possible.

When Should You Choose Interviews in a Dissertation?

Interviews are ideal when your dissertation question needs detailed, private, and personal insights that may not emerge in surveys or group settings.

1. When you are studying people's unique life stories and journeys

   • When to use interviews: You should choose interviews when your research is about understanding how someone's life unfolded over a long period. Interviews are like a time machine for a person's story, helping you explore how they changed and adapted.

   • For example:

     • In Sociology, a research question could be: "What is it like for a first-generation university student to adjust to campus life?" A survey might find out if they feel lonely, but an interview can reveal the deeper reasons and struggles behind that feeling.
     • In Psychology, a question might be: "How do retired athletes find a new sense of self after their career ends?" An interview can capture the feelings of loss, freedom, and personal meaning they attached to their sport.

2. When the topic is about personal or sensitive experience

   • When to use interviews: Interviews are the best choice when your topic is private, sensitive, or deeply personal. People might not feel comfortable sharing certain details in a written survey, but a confidential, one-on-one conversation can help build trust.

   • For example:

     • In Medicine, a research question might be: "What is the experience of patients going through infertility treatment?" Interviews allow patients to talk openly about their emotional ups and downs, their hopes, and their feelings of shame.
     • In Human Resources, a question could be: "How do employees describe their experience with workplace harassment?" Interviews can uncover subtle behaviors, the emotional impact, and the complex reasons why some people feel unable to speak up.

3. When you need to understand the "why" behind decisions

   • When to use interviews: A survey can tell you what people chose, but interviews are needed to find out why. When a decision involves complex thinking, weighing many factors, and personal beliefs, interviews are the tool to use.

   • For example:

     • In Business, a research question could be: "Why do small business owners resist adopting new digital tools?" An interview can uncover their detailed reasoning, revealing specific fears about cost, learning curves, or their own lack of skills.
     • In Education, a question might be: "What factors influence a parent's choice of private schooling?" Interviews can reveal the detailed thought process, including concerns about academic reputation, school safety, and personal values.

4. When you want to explore feelings and deeper meanings

   • When to use interviews: Interviews are perfect for exploring feelings, values, and the deeper meanings people attach to events. They allow for a more natural conversation where emotions can be expressed and understood, not just counted.

   • For example:

     • In Sociology, a research question might be: "What is the experience of belonging for migrants in a new city?" An interview can capture the feelings of relief in finding a cultural community, alongside feelings of alienation elsewhere.
     • In Health, a question could be: "How do nurses describe their experience with burnout?" An interview can distinguish between the physical tiredness and the deeper, emotional disconnection they feel from their work.

5. When you are exploring a new or under-researched topic

   • When to use interviews: If your research is in a brand-new area with very little information, interviews are the way to go (Mathers, Fox and Hunn, 2000). They can help you explore a topic and uncover ideas you might never have thought of on your own.

   • For example:

     • In Technology, a research question might be: "What are employees' first experiences with AI tools at work?" An interview can reveal initial feelings, excitement, fear, or frustration, and unexpected challenges or benefits.
     • In Consumer Behavior, a question could be: "What influences consumer attitudes toward plant-based meat?" Interviews can uncover the complex mix of health beliefs, environmental concerns, taste perceptions, and personal values.

6. When you want to compare different perspectives

   • When to use interviews: Interviews are excellent for comparing the personal experiences and views of different groups. They allow you to collect rich stories from each group and see where their experiences overlap or differ.

   • For example:

     • In Public Health, a research question might be: "What are the experiences of urban doctors versus rural doctors with patient care?" An interview can reveal how factors like resources, patient load, and community trust shape their medical practice.
     • In Workplace Studies, a question could be: "How do younger and older employees perceive remote work?" An interview can highlight different values, a younger person may value flexibility, while an older employee might miss the social aspect of the office.

II. What is a Focus Group?

A focus group is a small discussion group (usually 6–10 people) led by a researcher (Teufel-Shone and Williams, 2010). The goal is to listen to how people talk, argue, agree, and share their experiences about a certain topic. Instead of collecting answers one by one during one to one interviews, a focus group gives you the interaction, people remind each other of experiences, challenge opinions, and bring new ideas to the surface.

Think of it like sitting in a living room and saying: “Tell me what you all think about this issue.” Then you, the researcher, guide the talk.

Focus groups can be organised in different ways, depending on your dissertation needs:

• Online Focus Groups – Conducted over platforms like Zoom or Microsoft Teams. Useful when participants are in different locations or when face-to-face meetings are not possible.
• Structured vs. Unstructured Focus Groups – A structured group follows a strict set of questions, while an unstructured group allows freer conversation, guided only lightly by the researcher.
• Homogeneous Focus Groups – Participants share a key characteristic (e.g., all nursing students, all first-year teachers). This helps reveal shared experiences and group identity.
• Heterogeneous Focus Groups – Participants come from mixed backgrounds (e.g., men and women, urban and rural students). This highlights differences and brings out contrasting perspectives.

When Should You Choose Focus Groups in a Dissertation?

You don’t use focus groups for every project. They are the right fit when your research question is about opinions, feelings, shared experiences, or social dynamics.

1. When you want to understand a shared opinion or experience

   • When to use focus groups: This is the perfect approach for when your research is about understanding a shared event or a common feeling that many people experience. The group dynamic helps people feel more comfortable opening up and sharing stories that might not come up in a private conversation.
   • For example:
   • In Education, a research question might be: "What was the student experience during the COVID-19 lockdown?" One student's story about struggling with online learning might remind another of their own challenges, creating a richer, more detailed picture.
   • In Marketing, a question might be: "How do consumers feel about a company's eco-friendly packaging?" You can observe how opinions and concerns are expressed and debated in real time, like some people praising it while others worry about the higher cost.

2. When you want to see how social dynamics work

   • When to use focus groups: If your research question is about how people influence each other, a focus group is the right method. You can observe who speaks most, who agrees, and who disagrees, which tells you a lot about the group's social norms and power structures.

   • For example:

   • • In Organizational Behavior, a research question could be: "How do colleagues discuss blame when a project deadline is missed?" Some people may defend the team, while others point out failures. The group setting reveals these clashing dynamics.
     • In Sociology, a question might be: "How do young adults influence each other's decisions about recreational drug use?" A group setting allows you to observe how they debate, justify, or push back against each other's opinions.

3. When you need to compare perspectives between different groups

   • When to use focus groups: If your study compares the experiences of different groups, running separate focus groups for each group can be very effective. This allows each group to tell its own collective story, highlighting the unique aspects of their perspective.

   • For example:

   • • In Political Science, a research question might be: "How do younger and older voters discuss climate change?" The focus group with older voters might talk about a long-term responsibility, while the younger group expresses a greater sense of urgency and frustration.
     • In Health Services, a question might be: "How do urban doctors and rural doctors discuss patient care?" The rural doctors might focus on resource limitations, while the urban doctors talk about overcrowding and systemic issues.

4. When the topic is sensitive, but still a shared experience

   • When to use focus groups: Some difficult experiences are also shared by many people. Talking about them in a group of people who have gone through the same thing can provide a sense of safety and solidarity that encourages more honest sharing.

   • For example:

   • • In Trauma Studies, a research question could be: "How do disaster survivors describe the trauma and the process of rebuilding?" A focus group of survivors can openly share painful memories and collective coping strategies, creating a sense of shared resilience.
     • In Healthcare, a question might be: "How do cancer survivors talk about the fear of relapse?" In a group of fellow survivors, they can share coping strategies and fears without judgment, creating a supportive space.

5. When you are testing products, ideas, or services

   • When to use focus groups: If you have a new product, app, or service and want to see people's reactions, a focus group is a great way to gather immediate feedback. You can observe the group's natural discussion, laughter, or criticisms, which tells you far more than a simple survey.
   • For example:
   • In Technology, a research question could be: "How do students react to a new learning app?" You can see how some praise a feature while others complain about its complexity, revealing which aspects matter most to users.
   • In Marketing, a question might be: "What is the consumer reaction to a new advertising campaign?" Watching how the group responds to the ad can show you if it is authentic or misses the mark with the target audience.

6. When you are exploring a new or under-researched area

   • When to use focus groups: If your topic is so new that little is known about it, a focus group is a great way to brainstorm and gather different ideas quickly. The interaction can uncover themes and issues that you didn't even know existed.
   • For example:
   • In Psychology, a research question could be: "What features should a mental health app for teenagers include?" The teens in the group can bounce ideas off each other, suggesting practical tools and language that feel real to them, which would be hard to collect otherwise.
   • In Organizational Studies, a question might be: "How do workers describe their first encounters with AI tools?" The discussion can reveal initial feelings of excitement or fear, and unexpected ways the tool is being used or rejected.

III. What is Observation?

Observation is a research method where the researcher carefully watches people, actions, or settings and records what actually happens (Kumar, 2023). Unlike interviews or surveys, where people tell you what they think or do, observation lets you see behaviour directly. It is powerful when you want to understand routines, habits, or social interactions as they naturally unfold.

Types of Observation

Observations can be grouped in three simple ways:

• Role of the researcher – Participant (you join in) vs. Non-Participant (you only watch).
• Level of control – Structured (you use a checklist) vs. Unstructured (you take free notes).
• Awareness – Overt (people know you’re observing) vs. Covert (people don’t know, needs ethical approval).

When Should You Choose Observation in a Dissertation?

Observation is best when you want to see what people actually do, not just what they say. It lets you capture real behaviour, routines, and interactions in natural or controlled settings.

1. When Studying Natural Behavior in Authentic Settings

   Use observation when:

   You need to examine unscripted behaviors as they unfold in everyday environments where participants feel at ease.

   Why?

   People often behave differently when aware of being studied or questioned. Observation reveals genuine actions unaffected by self-consciousness.

   Examples Across Fields:

   • Education: What patterns emerge in children's playground equipment use during recess?
     → One group clusters at swings, while others dominate the football field.
   • Business: In what ways do shoppers navigate supermarket environments?
     → Some move directly to essentials, others wander through promotions.
   • Sociology: To what extent do commuter interactions vary on public transportation?
     → One passenger reads silently, while others engage in disputes over seating.
   • Healthcare: What characterizes patient dynamics in medical waiting rooms?
     → Some initiate conversations with strangers, others consistently avoid eye contact.

2. When Capturing Routines and Behavioral Patterns

   Use observation when:

   Your research requires understanding repeated habits or daily rhythms that participants may not consciously recognize.

   Why?

   People often cannot articulate their own automatic routines. Direct observation uncovers patterns they might overlook or forget to report.

   Examples Across Fields:

   • Nursing: How is time allocated by nurses during night shifts?
     → One checks patients regularly, another prioritizes administrative tasks.
   • Education: What techniques do teachers employ for classroom transitions?
     → Some use musical cues, others provide verbal instructions.
   • Workplace Studies: In what ways do office teams structure coffee breaks?
     → One team takes synchronized breaks, while another disperses individually.
   • Sports Science: What variations exist in athletes' pre-practice warm-up routines?
     → Some follow prescribed drills, others create personalized stretching sequences.

3. When Verbal Reports May Be Unreliable or Incomplete

   Use observation when:

   Participants might provide inaccurate, biased, or incomplete accounts of their own behaviors, especially regarding sensitive or socially sensitive topics.

   Why?

   Self-reported data often reflects desired behavior rather than actual conduct. Observation reveals discrepancies between words and actions.

   Examples Across Fields:

   • Child Psychology: To what degree do students adhere to classroom rules when unsupervised?
     → Some raise hands patiently, others whisper answers without permission.
   • Public Health: How do gym members actually use exercise equipment?
     → Some follow posted guidelines, others develop unconventional techniques.
   • Hospitality: What hygiene practices do restaurant staff implement during busy periods?
     → Some sanitize meticulously, others omit steps during rushes.
   • Urban Planning: How consistently do drivers comply with pedestrian crossing rules?
     → Some stop immediately, others accelerate despite clear signage.

4. When Examining Interpersonal Dynamics

   Use observation when:

   Your research focuses on how people communicate, collaborate, or conflict in real-time social exchanges.

   Why?

   Interactions involve nuanced nonverbal cues, timing, and contextual factors that interviews or surveys cannot fully capture.

   Examples Across Fields:

   • Early Childhood Education: What behaviors do toddlers exhibit during toy-sharing in daycare?
     → One child seizes toys forcefully, another engages in calm negotiation.
   • Business: To what extent is collaboration balanced during team projects?
     → Some distribute tasks equitably, others allow one person to dominate.
   • Family Studies: How do families interact during restaurant meals?
     → Some engage in lively conversation, others remain focused on mobile devices.
   • Management: In what ways do managers address conflict during meetings?
     → One de-escalates tension, another responds with confrontational language.

5. When Contextual and Environmental Factors Matter

   Use observation when:

   Physical spaces, tools, or surroundings significantly influence human behavior.

   Why?

   Environmental elements shape actions in ways people may not recognize or report. Observation captures how context drives conduct.

   Examples Across Fields:

   • Marketing: What differences exist in customer behaviors between luxury and budget stores?
     → Luxury shoppers browse leisurely, budget shoppers move with purpose.
   • Education: How do study habits vary between library and café environments?
     → Libraries foster silent focus, cafés encourage multitasking amid chatter.
   • Political Science: What behaviors do voters exhibit at polling stations?
     → Some deliberate carefully over ballots, others complete selections rapidly.
   • Event Management: To what extent do festival attendees follow crowd navigation guidelines?
     → Some follow directional signs, others create congestion by disregarding pathways.

6. When Tracking Behavioral Evolution Over Time

   Use observation when:

   Your research requires documenting how behaviors develop, adapt, or change across extended periods.

   Why?

   Gradual transformations often go unnoticed by participants. Longitudinal observation reveals subtle shifts and emerging trends.

   Examples Across Fields:

   • Education: How do students adapt to new seating arrangements over weeks?
     → Initial random seating evolves into established social groupings.
   • Rehabilitation: What progression markers appear during physiotherapy treatment?
     → One patient demonstrates consistent improvement, another struggles with exercises.
   • Entrepreneurship: In what ways do start-up teams' meeting practices evolve as projects grow?
     → Early brainstorming sessions gradually transition to structured agenda-driven meetings.
   • Urban Studies: What seasonal usage patterns emerge in public park spaces?
     → Winter attracts solitary joggers, summer draws families for picnics and group activities.

We have now completed the primary qualitative methods , interviews, focus groups, and observations , which involve collecting fresh stories and experiences directly from people. Now let’s move to secondary qualitative data collection methods, where instead of talking to participants yourself, you work with material that already exists.

(B) SECONDARY QUALITATIVE DATA COLLECTION METHODS

While primary methods such as interviews or focus groups involve collecting fresh data directly from participants, many dissertations also rely on secondary qualitative data collection (Dufour and Richard, 2019). This approach uses materials that already exist, produced for purposes other than your research, and reinterprets them to answer new questions. Secondary methods are especially useful when direct access to participants is difficult, or when historical or large-scale evidence is needed. Broadly, these methods fall into two main types:

1. Documentary Sources – written materials like government reports, organisational records, diaries, blogs, or academic publications.
2. Audio-Visual & Multimedia Sources – non-written materials such as photographs, documentaries, podcasts, news broadcasts, or digital videos.

I. What are Documentary Sources?

Documentary sources are existing written materials , both printed and digital , that researchers analyse to answer new questions (Bowen, 2009). These include government reports, company records, organisational case studies, newspapers, diaries, blogs, academic articles, and even archived transcripts or census documents. Instead of creating new data, you work with what has already been produced and interpret it for your dissertation.

Documentary Sources come in different forms

• Official Documents: Government white papers, legal records, policy guidelines, census reports.
• Organisational Documents: Company reports, internal memos, NGO case studies, mission statements.
• Personal Documents: Diaries, letters, autobiographies, personal blogs.
• Academic & Grey Literature: Journal articles, dissertations, conference papers, NGO reports.
• Digital Documents: Online news articles, social media posts, discussion forums, digital archives.

When Should You Choose Documentary Sources in a Dissertation?

1. When participants are hard to reach Use when: You need data about groups, organisations, or contexts that are inaccessible for interviews.

   For example:

   • Political Science: “How do government reports frame refugee integration?”
   • Healthcare Management: “What do hospital policy documents reveal about patient safety priorities?”
2. When studying historical or long-term change Use when: You want to trace ideas, policies, or attitudes across time.

   For example:

   • Education: “How have school textbooks represented Indigenous culture since the 1970s?”
   • Business: “How do company annual reports show the rise of sustainability language?”
3. When the topic requires large-scale evidence Use when: Analysing hundreds of documents provides broader patterns than a small interview set.

   For example:

   • Sociology: “What themes emerge in thousands of online blogs on infertility?”
   • Criminology: “How do court judgments describe workplace harassment cases over two decades?”
4. When ethical or practical limits restrict primary research Use when: Direct interviews may be too sensitive, costly, or risky.

   For example:

   • International Relations: “How do UN reports describe humanitarian crises?”
   • Media Studies: “How did newspapers portray the COVID-19 lockdown in its first year?”
5. When you want to compare texts across settings Use when: You are interested in similarities and differences in how documents frame the same issue.

   For example:

   • Public Policy: “How do different countries’ policy papers define digital literacy?”
   • HRM: “How do employee handbooks in startups vs corporates describe workplace culture?”
6. When working with archived or unique historical sources Use when: Archival data gives rare insights that can’t be collected again.

   For example:

   • History: “What do World War II letters reveal about family resilience?”
   • Sociology: “How do early census records capture migration trends?”

II. What are Audio-Visual & Multimedia Sources?

Audio-visual data are existing materials that communicate meaning through images, sound, or moving visuals rather than written text (Harun, 2025). These include photographs, documentaries, news broadcasts, adverts, recorded speeches, podcasts, webinars, and social media videos. In a dissertation, you don’t collect new recordings; you select and analyse already-available materials to interpret symbolism, identity, emotion, and public narratives.

Audio-Visual comes in different forms

• Still Images (Photographs/Posters): Press photos, campaign posters, archival family albums.
• Motion Picture (Documentaries/News/Ads): TV segments, brand films, public service announcements.
• Audio-Only (Speeches/Podcasts/Radio): Leaders’ addresses, health promotion radio spots.
• Digital-Native Video (Reels/Shorts/TikTok/YouTube): User-generated clips, influencer content, live streams.
• Screen-Based Events (Webinars/Recorded Conferences): Public talks, educational videos, panel discussions.

When Should You Choose Audio-Visual Sources in a Dissertation?

1. When you are studying representation and symbolism Use when: You need to examine how visuals and sounds construct meaning (gender, class, nation, brand identity). For example:
   • Cultural Studies: “How are migrant identities coded through costume and framing in mainstream films?”
   • Marketing: “Which visual motifs signal ‘sustainability’ in luxury brand ads?”
2. When the communication style matters beyond words Use when: Gesture, tone, pacing, music, or editing choices shape interpretation. For example:
   • Politics: “How do crisis speeches use tone and body language to project reassurance?”
   • Health Promotion: “How do anti-smoking PSAs use sound/imagery to evoke risk and urgency?”
3. When you want to explore identity and belonging as performed Use when: People “show” who they are via images/videos rather than tell it in text. For example:
   • Sociology: “How do diaspora communities express belonging on Instagram photo-stories?”
   • Anthropology: “What do wedding videos reveal about ritual and intergenerational norms?”
4. When historical/long-term visual change is central Use when: You need to trace how visuals evolved across decades. For example:
   • History of Education: “What do classroom photographs (1950s–2000s) show about pedagogy shifts?”
   • Environmental Communication: “How did documentary framing of climate risk change since 1990?”
5. When comparing portrayals across channels or formats Use when: You test differences between documentaries, news, ads, and short-form social video. For example:
   • Media Studies: “Climate change in documentaries vs nightly news: frames and emotional appeals.”
   • Business: “ESG messaging in brand films vs TikTok , depth vs virality trade-offs.”
6. When the topic is new or under-researched in digital culture Use when: Emerging platforms (Reels/TikTok) host primary meaning-making you can’t access otherwise. For example:
   • Technology & Society: “How do workers narrate first encounters with workplace AI in short-form videos?”

We have covered the main qualitative data collection methods and when to apply them in research. The next step is to focus on qualitative data analysis, where the goal is to turn raw information into meaningful insights. In this section, we’ll explore techniques to identify themes, interpret narratives, and link your findings directly to your dissertation research questions.

DATA ANALYSIS METHODS

What is Data Analysis?

Data analysis is the process of cleaning, examining, and interpreting the information you collected to make it meaningful (Dibekulu, 2020). In a dissertation, data analysis means taking your raw material, whether numbers from surveys, experiments, or datasets, or words from interviews, focus groups, or documents, and turning it into answers for your research question.

Think of it like cooking: data collection gives you the raw ingredients, but analysis is the stage where you mix, cook, and season them to create a final dish. Without analysis, your dissertation would just be a pile of uncooked ingredients, facts without meaning.

Just like data collection, data analysis methods are divided into two broad families: quantitative (numbers) and qualitative (words, meanings, stories).

Qualitative Data Analysis Techniques

1. Content Analysis
2. Thematic Analysis
3. Narrative Analysis
4. Grounded Theory Analysis
5. Discourse Analysis

1. Content Analysis

Definition

Content analysis is a qualitative research technique used to systematically organise and interpret textual or visual data by identifying recurring words, patterns, or themes (Y Sirilakshmi et al., 2024). In a dissertation, it allows you to take unstructured material such as interview transcripts, documents, or survey responses and convert them into meaningful categories that can be compared, explained, and presented clearly.

Major Categories of Content Analysis (with Dissertation Applications)

1. Conceptual Content Analysis Definition: Counts the frequency of specific words, phrases, or concepts. Dissertation use: If you analyse 200 student feedback forms, you might count how often “flexibility,” “stress,” or “interaction” appear to show dominant themes in online learning experiences.
2. Relational Content Analysis Definition: Examines how words or concepts are linked together in context. Dissertation use: In employee interviews, you might find “burnout” often appears alongside “long hours,” revealing how staff connect these ideas.
3. Inductive (Qualitative) Content Analysis Definition: Categories emerge naturally from the data, not from a pre-set theory. Dissertation use: When interviewing patients, new categories such as “trust,” “privacy,” or “fear of stigma” might appear without being pre-decided.
4. Deductive (Directed) Content Analysis Definition: Uses existing theories or frameworks to code the data. Dissertation use: Analysing workplace motivation interviews using Herzberg’s theory (hygiene factors vs. motivators) to classify employee responses.
5. Summative Content Analysis Definition: Combines word counts with interpretation of context and tone. Dissertation use: Studying 100 newspaper articles, you may find “sustainability” appears often but is framed negatively in some contexts and positively in others.

When to Use Content Analysis in a Dissertation

1. Summarising open-ended survey responses
   • Analysing “What do you like most about online learning?” answers
     → Codes: flexibility, convenience, lack of interaction.
   • Showing frequency of common responses to highlight what matters most to students.
   • Grouping repeated words into categories like advantages vs. challenges.
2. Analysing interview transcripts
   • Identifying repeated mentions of work-life balance in staff interviews to highlight key workplace concerns.
   • Coding parent interviews for categories like trust in teachers, concerns about safety, and expectations from schools.
   • Comparing how younger vs. older participants describe “job satisfaction.”
3. Examining policy documents or reports
   • Analysing how terms like equity and access appear in government education policies.
   • Tracking the language shift in WHO health guidelines from “prevention” to “digital solutions.”
   • Coding sustainability reports of corporations for recurring categories like environmental responsibility, CSR, and compliance.
4. Analysing media or social media content
   • Coding 1,000 tweets about climate change for mentions of urgency, policy, or blame.
   • Analysing online reviews of a product to see recurring words like pricey, durable, fast delivery.
   • Comparing how newspapers in two countries frame the term migration.
5. Comparing groups systematically
   • Student vs. teacher interviews
     → Students highlight stress; teachers highlight curriculum pressure.
   • Male vs. female responses in surveys
     → Men mention salary, women mention job security.
   • Comparing NGO vs. government publications to see how each frames poverty alleviation.
6. Tracking changes across time
   • Analysing news articles on AI between 2010–2025
     → earlier focus on efficiency, later focus on ethics.
   • Studying speeches from three different elections
     → shifting from development to national security themes.
   • Comparing academic journal abstracts before and after COVID-19
     → increase in terms like remote, resilience, adaptation.
7. Exploring underlying meanings beyond frequency
   • Analysing whether “flexibility” in job ads is framed as remote work (positive) or unstable contracts (negative).
   • Looking at how “sustainability” is discussed: as marketing strategy or as genuine responsibility.
   • Examining metaphors in teacher interviews (e.g., calling teaching “a battle” vs. “a journey”).
8. Profiling sub-groups in your study
   • Urban vs. rural respondents: Urban stress coded as traffic, rural stress coded as lack of facilities.
   • Undergraduates vs. postgraduates: Different categories emerge like career concerns vs. academic workload.
   • Employees in different sectors: IT workers emphasise innovation, healthcare workers emphasise patient safety.

2. Thematic Analysis

Definition

Thematic analysis is a widely used qualitative technique for identifying, analysing, and reporting themes within data (Kiger and Varpio, 2020). A “theme” represents a pattern of meaning that captures something important about the research question. Unlike content analysis, which often focuses on counting words or categories, thematic analysis digs deeper into the meanings and experiences expressed by participants. In a dissertation, it is often the preferred method when working with interviews, focus groups, or narrative data because it allows flexibility and depth in interpreting personal experiences.

1. Inductive Thematic Analysis

   Definition: Themes emerge directly from the data without using pre-existing theories.

   Dissertation use: Interviewing international students about adjusting to university life, and themes like culture shock, financial stress, and peer support naturally arise from their narratives.

2. Deductive Thematic Analysis

   Definition: Data is coded and interpreted using a pre-set theory or framework.

   Dissertation use: Analysing employee interviews about motivation using Self-Determination Theory as a guide (themes: autonomy, competence, relatedness).

3. Semantic Thematic Analysis

   Definition: Focuses on explicit, surface-level meanings in the data.

   Dissertation use: Coding teacher interviews for direct mentions such as “lack of resources” or “time pressure” without inferring deeper meanings.

4. Latent Thematic Analysis

   Definition: Focuses on underlying ideas, assumptions, and meanings beyond the surface.

   Dissertation use: In student focus groups, instead of only recording mentions of “stress,” the analysis identifies a deeper theme of systemic academic pressure.

3. Narrative Analysis

Definition

Narrative analysis is a qualitative approach that focuses on the stories people tell and how they tell them (McLeod, 2024). Instead of breaking text into isolated categories, it examines the structure, content, and meaning of entire narratives. The method assumes that human beings make sense of their lives through stories, and those stories reveal values, beliefs, and identities. In dissertations, narrative analysis is valuable when you want to capture individual experiences in depth, highlight personal journeys, or show how events are interpreted differently by participants.

4. Grounded Theory Analysis

Definition

Grounded theory analysis is a qualitative research technique used to develop a theory directly from data rather than starting with pre-existing frameworks (Tie, Birks and Francis, 2019). It is called “grounded” because the resulting concepts and theories are firmly rooted in the participants’ own words and experiences. In dissertations, grounded theory is particularly useful when you want to explain processes, build new models, or uncover how and why certain behaviours or social patterns occur.

5. Discourse Analysis

Definition

Discourse analysis is a qualitative method that studies how language, communication, and texts shape meaning, power, and social reality (Talja, 2025). It goes beyond the literal content of words to examine how things are said, what assumptions are embedded, and how language reflects or reinforces social structures. In dissertations, discourse analysis is often applied to interviews, media texts, political speeches, or institutional documents where the goal is to understand the underlying ideologies, power dynamics, or cultural contexts expressed through language.

6. Experimental Analysis

Definition

Experimental analysis in quantitative dissertations refers to testing, validating, and evaluating models or systems through controlled experiments, often using coding, programming, or technical simulations (Zelkowitz and Wallace, 2025). Instead of relying only on surveys or secondary data, this method involves building something (an algorithm, a network, a web system, or a cloud environment) and testing it under specific conditions to produce measurable results. In computer science, IT, and engineering dissertations, experimental analysis is essential because it demonstrates not only theoretical knowledge but also practical implementation and performance evaluation.
