In this lesson, students pose and answer a statistical question by designing an experiment, collecting data, and analyzing data. They determine how best to display data, select appropriate measures of center and variability, and answer a statistical question involving two different treatments.

Technology isn't required for this lesson, but there are opportunities for students to choose to use appropriate technology to solve problems. We recommend making technology available. When students choose an appropriate display for data and choose to use technology to calculate statistics, they are using appropriate tools strategically (MP5). Students make sense of problems and persevere in solving them (MP1) when they make sense of the situation in order to come up with a meaningful statistical question and then follow through to answer their question. Students also must select an appropriate variable to analyze for comparing student heights, which engages them in aspects of mathematical modeling (MP4).
