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.

  1. First, determine the upper limit of the data. 
  2. Next, determine the lower limit of the data. 
  3. Next, gather the formula from above = CS = UL – LL.
  4. Finally, calculate the Class Size.
  5. 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
