Which view shows ratings by demographic categories for a given factor?

• A. The bar graph showing the overall ratings and the ratings by demographics
• B. The pie chart of responses
• C. The line chart of monthly changes
• D. The table of raw numbers

Answer: (A)

When you want to compare how different demographic groups rate a single factor, you need a visualization that makes those group differences easy to read at a glance. A bar graph that shows the overall rating alongside ratings by each demographic category does exactly that. The bars provide a clear, side-by-side comparison, so you can quickly see which groups rate higher or lower and how each group relates to the overall average. This visual format is especially effective because it highlights disparities and patterns across demographics without requiring mental calculations.

Pie charts aren’t ideal for this purpose because they focus on parts of a whole and become unwieldy when comparing multiple groups for one factor. Line charts show changes over time, which isn’t the goal when looking at demographic differences for a single factor. A table of raw numbers gives exact figures but makes it harder to spot trends and differences quickly, especially across several groups.

So, the bar graph showing the overall rating and the ratings by demographics is the best choice for viewing ratings across demographic categories.
