Calculating the Class Midpoint for the Class 1-5

To calculate the class midpoint for the class 1-5, we need to find the midpoint between the lower and upper bounds of the class. The class midpoint is a crucial concept in statistics, as it allows us to represent the center of a class interval.

The Formula for Class Midpoint

The formula for calculating the class midpoint is:

Class Midpoint = (Lower Bound + Upper Bound) / 2

Applying the Formula to the Class 1-5

Using the formula, we can calculate the class midpoint for the class 1-5 as follows:

Class Midpoint = (1 + 5) / 2 Class Midpoint = 6 / 2 Class Midpoint = 3
