Histograms look similar to bar graphs, however they vary because each bar is connected in a histogram along the x-axis. Histograms use the y-axis to display information by using different heights to show different data. The histogram provided shows the number of girls and women who have bought a particular skirt from a clothing store. The information shows that women in between the ages of 16-20 bought the most skirts. By showing this information through bars that are connected, this graph can be considered a histogram.
