Screen Time Box Plot In-Class Assignment

About:

This in-class assignment guides students in grades 9 and 11 through collecting screen-time data from their class, calculating the five-number summary, and drawing a proportional box plot. Students then analyze the data for range, quartiles, and outliers, and apply their findings to real-world health implications about teen sleep and academic performance. Suitable for statistics units, homework collection with real data, or a one-period activity.
