The worked question on this page is original educational practice. It is not represented as a question from an official previous-year examination paper.
01 / UNDERSTANDING
Review the question
Write an original causal claim and build one relevant confounder, one genuine control and two unrelated facts as options for evaluation. The best evaluation fact should address the argument's specific weak link. An original checkpoint is: Which evidence most directly addresses the selection concern: similar baseline ability or a larger promotional poster? Supported answer: Similar baseline ability in the compared groups. Explain the decisive fact, then alter one condition and solve again. This is an original practice method, not a claim that the question appeared in an official past paper.
02 / UNDERSTANDING
The concept in context
An attractive explanation is not established merely because it fits the observation. Look for selection effects, reverse causality and omitted conditions before accepting causal language. A useful study check is to label the argument as causal, predictive, comparative or prescriptive, then identify which evidence changes the stated inference most directly. Explain why the method fits the stated facts before applying it to a changed situation.
03 / UNDERSTANDING
A worked learning case
A coaching group reports that learners who attend its optional quiz score higher in mocks. The observation alone cannot prove that quizzes caused the improvement: more motivated learners may choose the quiz. A stronger evaluation would compare similar starting scores and study time, or allocate participation fairly when feasible, then examine later performance.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Which evidence most directly addresses the selection concern: similar baseline ability or a larger promotional poster?
Show the answer and reasoning
Similar baseline ability in the compared groups.
The concern is that the quiz group started with an advantage unrelated to the quiz. Comparing baseline ability addresses one source of that imbalance, although other confounders may remain. Poster size supplies no relevant evidence about starting ability, participation choice or the causal effect on later examination performance.
Two traps to watch for.
- Treating a larger sample as an automatic cure for biased selection.
- Choosing evidence that repeats the conclusion rather than tests it.
