Question

Quizplus · Accepted Answer

Pie charts are effective in showing proportions or percentages of different categories that make up a whole. Each category represented in the pie chart is expressed as a slice of the pie, with the size of the slice corresponding to the relative frequency or proportion of that category in the overall data set. Since the total of all categories in a pie chart adds up to 100%, it is a useful way to represent frequencies that sum to a total.
