Which chart type would be most suitable for showing the frequency of categories in Excel?

The most suitable chart type for showing the frequency of categories in Excel is a pie chart. Pie charts effectively display the proportional representation of different categories within a whole, emphasizing how each category contributes to the total. Each slice of the pie visually represents the frequency or percentage of that category in relation to the entire dataset. This visual representation allows viewers to quickly grasp which categories dominate the dataset and how they compare to each other.

While a bar chart is also commonly used to show frequency data, it does so by depicting the frequency of each category as a rectangular bar. This can be effective for comparisons, but it does not visually convey the part-to-whole relationship as clearly as a pie chart. Line charts and scatter plots, on the other hand, are better suited for displaying trends over time or relationships between variables rather than categorical frequency.
