Enter the upper limit of the data and the lower limit of the data into the Calculator. The calculator will evaluate the Class Size.

## Class Size Formula

CS = UL - LL

Variables:

- CS is the Class Size ()
- UL is the upper limit of the data
- LL is the lower limit of the data

To calculate Class Size, subtract the lower limit of the data from the upper limit.

## How to Calculate Class Size?

The following steps outline how to calculate the Class Size.

- First, determine the upper limit of the data.
- Next, determine the lower limit of the data.
- Next, gather the formula from above = CS = UL – LL.
- Finally, calculate the Class Size.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

upper limit of the data = 10

lower limit of the data = 8
