Web1. First find the midpoint (M) for each group. Midpoint is the lower class limit plus the upper class limit divided by 2. The lower limit for every class is the smallest value in that class. On the other hand, the upper limit for every class is the greatest value in that class. 2. Multiply the frequency of each class by the class midpoint, f x M.
