               3.5   Unequal class sizes

               Histograms become more useful when we have unequal class sizes:

               0 – 5

               6 – 15

               16 – 25


               26 – 40

               Representing frequency by height alone can be misleading and a switch to areas
               (histograms) gives a fairer representation of the underlying data.
