Note: Bin size changes by dataset, but you
want it to be big enough so that you can see the
variability over the range of values, but not so
small that the histogram is too noisy to interpret.
Like box plots, you can also use multiple histograms to compare
distributions. In one last return to the flight data, Figure 4-59
shows the distributions of arrival delays for major airlines.
Delays of more than 15 minutes are highlighted in orange.
