Histograms are very similar to bar graphs, but instead of categories on the x axis and spaces between the bars, there are numbers on the x axis and no spaces between the bars. Histograms graphically display number ranges of data using bars of different heights. This example shows the number of girls/women who bought a certain skirt from a clothing store, and basically it just shows that the girls in the 16-20 year old group, bought the most of the certain type of skirt and the girls in the 1-5 year old group bought the least amount.
