Study Tips
- 1
Always include context in your answers — "the mean" earns no marks, "the mean number of hours slept per night" does.
- 2
Know the conditions for every inference procedure: normality, independence, and randomness. Check all three before every test.
- 3
Hypothesis test structure: State hypotheses → Check conditions → Calculate test statistic → Find p-value → Conclude in context.
- 4
The investigative task rewards students who can link multiple ideas together. Don't panic — read it carefully and use what you know.
Past Exam Questions
A study found a correlation of r = −0.82 between hours of TV watched per week and GPA. A student concludes that watching television causes lower grades. Explain two flaws in this conclusion.
Common Mistakes to Avoid
- ✕
Memorizing procedures without understanding when to use them — exams disguise familiar problems in new contexts.
- ✕
Skipping steps in working, which throws away method marks when the final answer is wrong.
- ✕
Not sanity-checking answers for reasonableness (wrong units, impossible magnitudes, extraneous solutions).
