In order to tabulate a large number of scores, we use the grouped frequency distribution table. In this method the scores are grouped or classified into small groups. These small groups are called class intervals. The lower value of the class interval is called the lower limit and the upper value of the class interval is called the upper limit. The size or width of the class interval is defined from the difference between the upper limit and the lower limit of a class interval. The average of the upper limit and the lower limit is called the mid value of that interval.

In general, in a grouped frequency distribution, all class intervals are equal in size. The number of scores falling under each class interval is recorded by putting tally marks (‘l’) The number of tally marks in a given class interval represents the frequency of that class interval.
