pdf Comparing The Mean And Median

This worksheet engages students in comparing the mean and median within a real-world data investigation. Students analyze plant growth data collected over four weeks and calculate both measures of center for different time periods. Using a structured table of plant heights, students determine the mean and median after week 2 and week 4, then compare the differences between the two measures.

Beyond simple computation, students must interpret what the differences between mean and median reveal about the data set. They also analyze changes in average growth from week to week, determining which time span shows the greatest and least mean increase. This progression strengthens understanding of how measures of center describe distributions and how averages can change over time.

Because the activity blends calculation, comparison, and interpretation, it promotes deeper reasoning about data rather than isolated skill practice. It works well as class discussion material, independent practice, performance assessment, or enrichment within a statistics and data analysis unit.
