Consider the following scores of data:
1, 5, 8, 8, 6, 6, 1, 8, 6, 8, 1, 8.
The number of times a particular score occurs in a data is called the frequency of that score.
1 occurs 3 times ⇒ 3 is the frequency of 1
5 occurs 1 time ⇒ 1 is the frequency of 5
6 occurs 3 times ⇒ 3 is the frequency of 6
8 occurs 5 times ⇒ 5 is the frequency of 8
