Prepare a complete frequency distribution table, that is, a table having a frequency, relative frequency, percentage, and a cumulative frequency columns.
Explanation / Answer
A frequency distribution table lists out the various observations of a variable together with their corresponding frequencies
The process of preparing a frequency distribution table involves listing of the various observations of the variable For example Marks secured by students of a class in a slip test 0,1,2,3,4,5,so on upto the maximum marks.
Then the number of students securing identical marks are indicated as the frequency of the marks concerned If seven students got 5 marks each then the frequency of the marks 5 shall be taken as 7
The table with the variable and frequency is termed as frequency distribution table
In case there is large difference between the largest and smallest items the variable may be shown in the form of classes
For ex. 0 to 10, 10 to 20, 20 to 30, so on...Then the students securing marks between the limits of the class shall be taken as frequency
