Sampling

2. (6 words _ _ of the _ _) — distribution of p across all samples of size n.
4. the entire group of interest for a study.
5. (2 words)the variation in a statistic from sample to sample.
8. (6 words -- of the --) distribution of barx across all samples of size n.
10. a numerical summary of a population (e.g., population mean).
11. systematic error that causes a statistic to consistently over- or under-estimate the parameter.
12. (CLT)the principle that, for sufficiently large sample size, the sampling distribution of the sample mean is approximately normal regardless of the population distribution.
13. (2 words) a statistic whose expected value equals the true population parameter.

1. a numerical summary computed from a sample (e.g., sample mean).
3. (2 words) a measure of spread that quantifies variability in a distribution; for a sampling distribution, the SD measures how much the statistic varies from sample to sample.
6. (LLN) the theorem that as sample size n increases, the sample mean barx tends to get closer to the population mean .
7. (2 words) the probability distribution of a statistic over all possible samples of a given size from a population.
9. a subset of the population used to draw conclusions.
