Final answer:
Jason should use data bars to add visual comparison data to a table. Data bars, or bar graphs, clearly illustrate comparisons by the length of each bar, and pie charts can be used for showing parts of a whole.
Step-by-step explanation:
Jason should consider using data bars as a visual representation in a table to easily show comparison data. Data bars, also known as bar graphs, can effectively illustrate patterns, comparisons, and trends within a dataset. The length of the bar for each category denotes the number or percent of individuals in that category, providing a clear visual comparison.
Furthermore, if Jason is working with parts of a whole, he could also use pie charts to show the categories of data by wedges in a circle, which represent the percentage of the individuals or items in each category.
