Quizplus · Accepted Answer

The graph described in the question is a line graph. It is used to show the differences in frequency or percentage among categories of an interval-ratio variable by joining points representing the frequencies above the midpoint of each category. A bar graph is used to compare different categories and display the frequency or percentage using bars. A pie chart is used to show the proportion of each category in relation to the whole. A histogram is used to show the frequency distribution of a variable with continuous data.
