What does a stacked column chart display?

• A. It shows only individual data points.
• B. It shows averages.
• C. It shows cumulative data for grouped categories, like regions, in a visually cleaner format.
• D. It shows only totals.

Answer: (C)

Stacked column charts focus on cumulative data across grouped categories. Each category is represented by one column whose height shows the total value, but that column is made up of colored segments that represent subgroups. This lets you compare overall totals across categories (like regions) while also seeing how each subgroup contributes to those totals in the same view. It’s not just individual points, nor just averages, and it isn’t limited to totals since you can see the breakdown inside each total.
