Grouped Data, Frequency Polygon

The table P, below, shows the weights of 182 students. If you highlight and change the weight
data and observe that the value of MIN(P) or MAX(P) changes to a new value, then you must
change the values of Minimum or Maximum manually. Minimum must always match MIN(P)
and Maximum must always match MAX(P). Your choice of the NumberOfClasses should be in
the range of 5 to 15. When you highlight the right-hand side of NumberOfClasses and choose a
different value, the statistics in table F will also change. The first column of F gives the class
marks, the second column shows the number of student weights in the corresponding class, and
the third column gives the corresponding relative frequency.
