Introducing Sample Proportions

Published on 06/15/2016

Activity Overview

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.

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

Vocabulary

population parameter, population proportion, random sample, sample statistic, sample proportion, random variable, estimation
