Question

How do you find the width I need the class width

Answer 1

In a frequency distribution, class width refers to the difference between the upper and lower boundaries of any class or category. It is calculated as:

`Width=(greatest-lowest)/(n)=(65-45)/(7)=2.85`

Where "greatest" and "lowest" are the greatest and the lowest numbers of the whole set of data, and "n" is the number of classes. Hence, the class width is 2.85
