What does a grouped column chart compare?

• A. It compares two metrics or variables side-by-side in separate columns
• B. It shows related metrics stacked on top of each other in a single column
• C. It displays the percentage of a total as slices
• D. It demonstrates a frequency distribution

Answer: (A)

Grouped column charts place multiple data series in each category as separate bars, so you can compare two or more metrics side by side across the same categories. Each category on the axis has a cluster of adjacent columns, one for each metric, making it easy to see how the values differ within a category and how they compare across categories. This contrasts with stacked column charts, which stack the series in a single column and can obscure individual contributions; a pie chart shows percentages of a total; and a chart showing a distribution highlights frequency of values rather than direct side-by-side comparisons. So, this chart type is best for comparing two metrics or variables side-by-side in separate columns.
