What outcome does grouping data into regions and using a stacked column chart achieve?

• A. It displays cumulative data for grouped categories in a cleaner format.
• B. It hides data.
• C. It doubles the number of data points.
• D. It makes the chart harder to read.

Answer: (A)

Grouping data by region and reading it in a stacked column chart lets you see the total value for each region while also showing how each category contributes to that total. This arrangement makes regional comparisons easy at a glance and reveals the composition within each region, so you’re viewing cumulative data for the grouped categories in a cleaner, more organized way. It doesn’t hide data or double points, and when the number of categories is kept reasonable, readability improves rather than worsens.
