A histogram is the appropriate graph for displaying the differences in frequencies or percentages among the categories of an interval-ratio variable where the categories are displayed as contiguous bars with width proportional to the width of the category and height proportional to the frequency or percentage of that category. A bar graph is better suited for displaying categorical data, a pie chart is better suited for displaying proportions that add up to 100%, and a frequency polygon is used to display the continuous distribution of a variable.
