This activity focuses on estimating population means which is a central activity in statistics. Using smaller samples statisticians often attempt to infer population parameters. This activity helps the learner understand the important concepts of what a population is, how it is measured, how measurements in statistical error occur, and what they mean for the interpretation of the results.
Article Analysis
Locate a news article or report (in a popular news source such as Time, Newsweek, or the Wall Street Journal) in which a population mean is estimated from a sample. The article should include a margin of error and confidence interval. Discuss the subject matter in the article, and interpret the results and what the confidence interval and margin of error mean as they apply to the specific subject matter.
