Identifying populations, samples and bias, and estimating a population figure from a sample.
Author note — to cover
- Fluency — naming the population and the sample in a described study, and choosing between a census and a sample (4 questions).
- Sampling methods — single-choice questions naming the method used and picking the least biased way to sample a described population (4 questions).
- Estimating and bias — scaling a sample proportion up to a population estimate with counts that divide exactly, ending with a large biased sample that stays biased (4 questions).
