11. REFLECTION: Make a histogram that represents the number of students of each age at
the same school who drive to school each day (either in their own car or riding with
friends). Describe the center, shape, and spread of your histogram.
Several of the previous histograms, including the one in Question 10, had a set interval width
(for example, the ages of bus riders in intervals of one year). Now you will investigate the
effect that interval width (also known as bin size) can have on a histogram as well as on a
reader of the histogram.
