Construct a grouped frequency distribution for the following 28 scores using a class width of 4:
64 63 58 46 52 62 47 49 56 47 43 41 45 51
60 62 51 61 50 55 56 53 54 58 48 48 58 46

A grouped frequency distribution is a chart that displays the frequency of data that is grouped into intervals. To construct a grouped frequency distribution for the given set of 28 scores that has a class width of 4, create a chart that contains the intervals—in this case, starting from a minimum of 43 and going up to a maximum of 64—and the frequency or count of the scores that fall within each interval. This table will look something like this: Interval|Frequency 43-46 | 4 47-50 | 5 51-54 | 5 55-58 | 8 59-62 | 7 63-64 | 3
