Find the mean of this frequency distribution: 1. The first thing you need to do is to find the midpoint for each class.
3. Finally divide the total of the Midpoint * frequency column by the total of the frequency column to get your mean. 1940 / 60 = 32.333333333... Always round to one value beyond what your original data was (since our classes were whole numbers we should round to 1 decimal place). So our final answer for the mean of this frequency distribution is 32.3. |
