# Class Width Calculator

The difference between the upper or lower class limits of consecutive classes is the class width. All classes should have the same class width and it is equal to the difference between the lower limits of the first two classes. Use the below online Class width calculator to calculate the Class Width Frequency Distribution. It is calculated by subtracting Maximum Value (x) with Minimum Value (y) and divide it by Number of Classes (n).

#### Formula:

Class Width = (x - y) / n
**Where,**
x = Maximum Value
y = Minimum Value
n = Number of Classes
### Example:

Calculate class width for 3 data items having a maximum value of 9, minimum value of 5.

#### Solution:

Class Width = (x - y) / n

= (9 - 5) / 3

= 1.333
