By the Class Interval?

Class interval refers to the numerical width of any class in a particular distribution. Mathematically it is defined as the difference between the upper-class limit and the lower class limit. Class interval = upper-class limit - lower class limit.

How do you find the class interval?

Class Interval = Upper-Class limit – Lower class limit. In statistics, the data is arranged into different classes and the width of such class is called class interval.

What is class interval example?

The class interval is the difference between the upper class limit and the lower class limit. For example, the size of the class interval for the first class is 30 – 26 = 4. Similarly, the size of the class interval for the second class is 31 – 35 = 4.
