Class Limits are upper and lower limits which contains a set of scores in a frequency distribution.
The upper class limit of one class and the lower class limit of the next class have a difference.
Class boundaries do not have a difference. This can be best explained with the help of the following example . Suppose we have a data and the frequency table
Time
Class Limits Class Boundaries Frequency
1-5 0.5- 5.5 5
6-10 5.5- 10.5 13
11-15 10.5- 15.5 6
16- 20 15.5- 20.5 8
21-25 20.5- 25.5 5
As shown above the class limits have a difference and class boundaries do not have a difference between the upper limits of the previous class lower limits of the next class.
