Find the midpoint of the line segment with the given endpoints: (negative-5.1, negative-2) and (1.4, 1.7).

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.
