What does the Class Midpoint represent?

The Class Midpoint is defined as the value that lies halfway between the upper and lower class limits of a given class interval. This midpoint serves as a representative value for that class interval and is critical in statistical analysis, particularly when dealing with grouped data. By calculating the midpoint, analysts can simplify complex data distributions and facilitate computations like estimates of the mean or the calculation of modal class.

For example, if you have a class interval of 10-20, the midpoint would be calculated as (10 + 20) / 2 = 15. This value of 15 is considered a concise representation of all data points falling within the range of 10 to 20.
