Which graphic or chart best supports a conclusion by providing data?

• A. A diagram that contains no numbers
• B. A chart or diagram that provides data backing the claim
• C. A decorative illustration
• D. An anecdote from a single source

Answer: (B)

Data-backed visuals that present measurable information are what really support a conclusion. When a graphic shows numbers—counts, percentages, trends over time—it lets readers see the actual evidence used to reach the claim. This kind of data visualization helps verify and compare details, making the conclusion more credible because it’s grounded in real measurements.

An illustration that has no numbers doesn’t provide that evidence, so it can’t show how strong or weak the claim is. An anecdote from a single source might feel convincing, but it’s only one example and may not represent the larger situation. A decorative image doesn’t offer evidence at all. By presenting data clearly, the chosen graphic gives readers a basis to evaluate the claim themselves, which is why it best supports a conclusion.
