A histogram represents the frequency of occurrence of data in a continuous or discrete interval. The variable that is plotted on the x-axis (horizontal axis) is continuous and takes a range of values, while the variable on the y-axis (vertical axis) represents the frequency or count of data falling within different intervals. Therefore, a histogram requires only one variable, which is represented on the x-axis.
