Study design, uncertainty and conclusions
What to know
Common mistake
Treating correlation as proof of causation
Worked example
A survey from one volunteer club estimates support across an entire city. What limitation should be named?
Data, probability and inference exam practice
What to know
Common mistake
Starting with a memorised method before checking what the question asks for.
Worked example
A Data, probability and inference question gives a graph, equation and context. What should the first working line do?
Sampling, experiments and bias
What to know
Common mistake
Claiming causation from an observational study
Worked example
A school survey asks only volunteers in the cafeteria. What concern should be named?
1. What skill does the approved sample question test?
ap statistics
Compare the p-value with alpha. Since p < alpha, reject the null. The conclusion must refer to the real situation, not just the symbols.
2. What mistake should you watch for in Study design, uncertainty and conclusions?
Treating correlation as proof of causation
StudyVector stores common mistake patterns so the next attempt can repair the specific error rather than restart the whole course.
3. What should happen after a missed point?
Review the explanation, name the mistake, then answer a similar question while the correction is fresh.
The page feeds the same loop as practice: attempt, feedback, repair, and return.
