Big Ideas: The margin of error is indirectly proportional to sample size. The margin of error measures the accuracy of a sample statistic and can be used with the sample statistic to estimate the population parameter. In previous lessons, students learned how to choose a sample and to generate survey data from a sample. In this lesson, students will determine a margin of error based on the sample size and then interpret this margin of error in terms of the given scenario. This lesson prepares students for future lessons approximating confidence intervals and comparing two different populations. Vocabulary: margin of error, population proportion, population parameter, confidence interval Special Materials: None
