Question

Quizplus · Accepted Answer

A bar chart is the best way to illustrate the frequencies for each political preference as it displays the frequency or count of each category as height or length of the bars. This allows for easy comparison of the frequencies of different political preferences. Pie charts, histograms, and frequency polygons are not as effective for displaying frequencies of categorical data.
