In this multi-step project, students become the Chief Data Analyst for the US Census Bureau Chief and write a report for a governor of a US state to answer the following question: “Are families in my state better or worse than 10 years ago?” Students will use educational technology and real US Census data. Students will learn how to make representative samples using random sampling to make valid statistical inferences comparing sample means. In Part 4, students make statistical inferences after executing t-tests for both differences in sample averages and sample proportoins.
