The midpoint of each class interval is called the class midpoint and is sometimes referred to as the class mark It is the value halfway across the class interval and can be calculated as the To calculate the estimated mean of the data the formula is frac sum m cdot f sum f where m midpoint of the class intervals and f frequency However the main point of
The mean is the sum of the product of the midpoints and frequencies divided by the total of frequencies Cumulative frequencies are obtained by the formula F m n 1 where m is the m th value in order of magnitude of the series and n is the number of terms in the series
