Objectives
- To appreciate variability in the results obtained from different random samples
- To investigate estimates of a population proportion from sample proportions
- To establish the idea of the sample proportion as a random variable
- Informally investigate the standard deviation of the sampling distribution
Vocabulary
population parameter, population proportion, random sample, sample statistic, sample proportion, random variable, estimation
About the Lesson
In this activity, simulated random sampling is used to develop the concept of the sample proportion as an estimator of the population proportion. Simulation will allow us to investigate how a sample proportion varies from sample to sample and an informal look at how the standard deviation changes with different sample sizes.
