In plain EnglishAI study guide · check the NZQA standard
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.
What to do, grades and common mistakes
What you actually do
- ·Read reports carefully and identify whether studies are experimental or observational, and what that means for what conclusions can be drawn
- ·Calculate and interpret confidence intervals and margins of error in context, clearly stating what population and variable you're talking about
- ·Identify design problems (like confounding variables, order effects, response bias, or incentives) and explain how they actually affect the results
- ·Spot when results are being improperly generalized beyond the study's actual scope, and explain why that's a problem
- ·Use precise statistical language (like 'reduce bias' not 'eliminate bias') and link all your observations directly back to the report's context
AAchieved
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.
