What graphs are used to represent Frequency Distribution?

• A. Box Plots and Pie Charts
• B. Histogram - Bar Graph; Frequency Polygons - Line Graphs
• C. Scatter Plot and Area Chart
• D. Radar Chart and Donut Chart

Answer: (B)

Frequency distribution is represented using histograms and frequency polygons. A histogram is a bar graph where data are grouped into equal-width intervals (bins), and the height of each bar shows how many observations fall into that interval. This makes the overall shape of the distribution—such as skewness, modality, and spread—clear. A frequency polygon takes the same interval midpoints and plots their frequencies as points, then connects those points with straight lines, producing a continuous outline of the distribution’s shape. Other charts don’t capture the distribution in this way: box plots and pie charts summarize aspects like spread and proportions, not the full frequency distribution; scatter plots and area charts depict relationships or cumulative totals; radar and donut charts aren’t used to display how often data occur across intervals.
