Quizplus · Accepted Answer

A frequency polygon and a histogram both represent the distribution of numerical data. Whereas dots connected by lines represent the frequency polygon, in which dots are connected by straight lines to display the frequency of data points in a continuous line, the bar graph represents the histogram, in which vertical or horizontal bars are drawn for each class interval, and their height represents the frequency of data points. Therefore, the best choice is a histogram.
