Class Size
Here we will learn class size.
The class size of an overlapping or nonoverlapping class interval
= Actual upper limit – Actual lower limit
= Difference of class boundaries.
For example: The class size of the overlapping interval 10 - 20
= Actual upper limit – Actual lower limit
= 20 – 10
= 10.
The class size of the nonoverlapping class interval 1 – 10 (when the intervals are 1 – 10, 11 – 20, 21 – 30, etc.)
= Actual upper limit – Actual lower limit
= 10.5 – 0.5
= 10.
