Which elements should be included when presenting data to support a policy proposal?

• A. Data sources, key metrics, limitations, and visuals.
• B. A handful of anecdotes without sources.
• C. A lengthy narrative with no figures.
• D. Data that only support your conclusion, ignoring counter-evidence.

Answer: (A)

When presenting data to support a policy proposal, the key is to build credibility through transparency and clear evidence. The best approach includes citing data sources so others can verify where the numbers come from and assess their reliability. It also shows what was measured and why it matters for the policy by listing the key metrics, making the relevance and scope explicit. Acknowledging limitations is crucial because it reveals what the data cannot capture, what assumptions were made, and any potential biases or uncertainties. Finally, using visuals helps the audience grasp patterns, comparisons, and trends quickly and reduces misinterpretation, making the argument more accessible to decision-makers.

Together, these elements empower others to evaluate the argument, understand how conclusions were reached, and weigh the policy’s potential impacts under different conditions. They also encourage honesty about gaps and trade-offs, which strengthens the overall case.

Avoiding anecdotes without sources is important because they aren’t generalizable and can’t be independently assessed. A lengthy narrative with no figures lacks the concrete, reusable grounding policymakers rely on. Presenting data that only supports the conclusion while ignoring counter-evidence undermines credibility and obscures important uncertainties.
