Evaluate statistically based reports
This standard asks you to read and critically evaluate statistical reports by checking whether the study design is sound and whether the conclusions drawn are properly supported by the data. You'll need to spot potential problems like bias, confounding variables, or incorrect generalizations, and explain why these issues matter to the strength of the findings.
You calculate confidence intervals or margins of error correctly and identify basic issues in the study design, but your explanations lack depth or don't clearly connect back to how the problems actually affect the conclusions.
You calculate confidence intervals correctly and interpret them in context, identify design issues and explain their impact, and use appropriate statistical language most of the time, but your responses may have minor gaps in formal structure or precision.
You calculate and formally interpret confidence intervals with full population and variable detail, explain both the 'why' and 'how' of design choices and their effects, use precise statistical language throughout, and coherently address all required parts of the question—calculation, interpretation, and claim—in context.
