Big Ideas: When comparing two different populations where the sample statistic for population A is greater than the sample statistic for population B, if the confidence intervals overlap, it is possible that the population parameter for population B could be greater than the population parameter for population A. In earlier lessons, students have learned to approximate confidence intervals using simulations and sample statistics. In this lesson, students will approximate confidence intervals using simulations for 2 different populations. Students will then compare the two populations with the intent to come to an understanding of what it means when confidence intervals do, or do not overlap. This lesson prepares students for more in-depth comparisons of different populations and interpretation of results. Vocabulary: margin of error, population proportion, population parameter, confidence interval Special Materials: Spreadsheet application
