Which statement about the histogram is true?
The majority of Maria’s runs were short, two-mile runs.
More than half Maria’s runs were less than five miles each.
The majority of Maria’s runs were between five and six miles.
At least 15 of Maria’s runs were more than four miles each.

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
