What is the benefit of reducing the number of slices in a pie chart?

• A. It increases data complexity.
• B. It makes the chart easier to read and interpret.
• C. It hides data.
• D. It uses more colors.

Answer: (B)

Reducing the number of slices in a pie chart makes it easier to read and interpret. When there are many categories, tiny slices can be hard to distinguish and labels may crowd the chart, so people struggle to compare proportions quickly. Fewer slices highlight the larger segments, improve visual contrast, and let you place labels clearly, which helps people understand the main results at a glance. If needed, smaller categories can be grouped into an “Other” category to keep the overall story intact while reducing clutter. The other options don’t fit because increasing data complexity isn’t the goal of simplification, pie charts with many slices don’t hide data, and using more colors isn’t a benefit of reducing slices (fewer slices usually means fewer colors).
