A histogram is a bar graph that has the data of frequency for the variable vertically and the classes to which the variable has been divided into is visible horizontally, with the width of each bar. The graph above shows the classes with respect to height in inches, while the frequency is visible on the left, vertical side of the graph. The graph shows a study done by UVM in order to see the frequency of height among 25 students.
