Frequency Table
Frequency table is a table which records the lists of items and uses the tally marks and shows us the number of times they occur. Here, each item contains its own particular frequency and each frequency are distributed with an interval between them. In simple words, a tabular display of frequency distribution is called as frequency table.
There are two types of frequency table:
Univariate Frequency Table:
In univariate frequency table, the frequency distributions are displayed as the lists ordered by quantity showing the number of times each value occurs.
Example: If we have a class of 10 students and asked them their favorite subject, then the univariate frequency table is displayed as follows:
Subject | Number of students |
Maths | 2 |
Science | 3 |
Social | 1 |
English | 4 |
Joint Frequency Table:
In Joint frequency table, the frequency distributions are displayed in two-way table. The total row and the total displays the marginal frequencies, while the body of the table displays the joint frequencies.
Example:
Dance | TV |
Sports | Total | |
Men | 4 | 8 | 10 | 22 |
Women | 5 | 12 | 8 | 25 |
Total | 9 | 20 | 18 | 47 |
