Which statement best describes methods of data analysis?

• A. Rely on rumors
• B. Make sure things are actually happening
• C. Use only anecdotal evidence
• D. Ignore data quality

Answer: (B)

Reliable data analysis starts with confirming that what you’re analyzing actually reflects what happened. This means verifying that events and measurements exist in the real world and are supported by evidence, not just beliefs or rumors. Relying on rumors or using only anecdotal evidence would lead to biased or incomplete conclusions because those sources aren’t representative or verifiable. Ignoring data quality undermines the analysis, since errors, gaps, or inconsistencies in the data distort findings. Therefore, grounding analysis in what is actually happening and in high-quality, verifiable data yields the most trustworthy conclusions.
