How can you evaluate whether a cited statistic is credible?

• A. Check the source, date, methodology, sample size, and whether it’s accurately represented in the text.
• B. Accept it if it is accompanied by a chart.
• C. Assume it is credible if the author cites other statistics.
• D. Dismiss it if the statistic seems complex.

Answer: (A)

To evaluate a cited statistic, trace it back to its original source and examine how it was generated. Look for a reputable, up-to-date source and check the methodology: who was studied, how participants were selected, what data were collected, and what potential biases might exist. Consider the sample size and whether it represents the population meant by the statistic. Verify that the text presents the statistic accurately and in proper context, including clear definitions, any caveats, and whether margins of error or confidence intervals are reported. Charts or references to other statistics can be misleading on their own; what matters is transparent methods and clear sourcing. When these elements align, the statistic is more credible.
