What is a Frequency Distribution Table?
A Frequency Distribution Table refers to a chart that recapitulates all the values and their frequencies. Preparing a Frequency Distribution Table is the best way to organize and manage the data. This further makes the information easy to read for the users. An ideal Frequency Distribution Table comprises of the two columns. The initial column presents all the results that come out from that particular information and the second column consists of the frequency of every unit or value. This kind of statistical data makes it easier for the readers to understand the concept.
What are the Advantages of Frequency Distribution Tables?
Frequency Distribution Tables are considered to be useful to explain the number of happenings of a specific type of unit within the information. Frequency tables are also known as Frequency Distribution Tables and are one of the basic essentials to showcase descriptive figures. With the help of Frequency Distribution Tables, you are able to find out evident inclinations within the statistical information and can be used to make a comparison as well.
• Rapid Data Visualization
The Frequency Distribution Table s have the ability to rapidly expose the outliers and other important trends of the statistical data.
• Visualizing Relative Abundance
The Frequency Distribution Tables have been designed to help the researchers in evaluating the relative abundance of every target statistics within the information. The relative abundance helps in presenting how much of the data set is included of the total target data. The relative abundance is often presented in the form of frequency histogram.
Presenting a particular set of statistical information in the tabular form that reflects the division of the information in the form of classes or groups, along with the frequency of occurrences in every class or group is known as the Frequency Distribution Table. The class frequency is referred to as the number of happenings in a specific class. The data that is presented in the form of the frequency distributions are known as grouped data while the data that is available in the original form is known as ungrouped data.
Take a look at some basic rules that you must consider at the time of preparing a grouped Frequency Distribution Table.
1. Number of Classes
The number of classes are highly dependent on the size of the statistical information. Usually, the number of class is kept between 5 and 20. If you add several classes then the major purpose of the data distribution into logical information will be ruined. On the other hand, making use of very few classes will not be able to bring out the complete information. Thus, there is a mere need to maintain the right balance.
2. Range of Variable
In order to choose the right number of classes, it is necessary to find out the range of the variable information by considering the change between the maximum and the minimum values of the statistical data.
3. Class Interval – Divide Range by Number of Classes
In order to study the estimated width or class interval, you need to divide the range by the number of classes. This will further provide us equal class intervals. If equal class-intervals are considered troublesome, then you have to make use of unequal sizes. You can consider online help to know how to calculate the class intervals.
4. Determine the Class Limits
The lowest class usually begins with the least data value or any number less than that. It is considered best if the class limits are a multiple of class-intervals. By totaling the size of the class-interval to the lower class boundary, you will be able to determine the upper class boundary. Adding the class-interval repeatedly, you will be able to find out the left out class-limits and class-boundaries.

5. Distribute Data into Classes
Tally-column is the best way to distribute the statistical information into appropriate classes in which all the values are represented in a tabular form. The number of tallies is then written in the frequency column of the Frequency Distribution Table.
