pdf Creating Box Plots From Test Scores

This worksheet provides structured practice creating box-and-whisker plots from real-world test score data. Students are given four different class score lists ranging from 16 to 29 data points and must organize the data, determine the five-number summary (minimum, Q1, median, Q3, maximum), and accurately construct a box plot on a number line scaled from 0 to 100.

Because the data sets vary in size and distribution, students must carefully sort each list and determine quartiles correctly for both even and odd numbers of values. The larger sets encourage precision and persistence, while the consistent 0–100 scale allows students to visually compare spread, clustering, and overall performance patterns across groups.

This resource strengthens students’ ability to move from raw numerical data to graphical representation while reinforcing understanding of distribution, variability, and measures of center. It works well as guided practice, independent work, homework, or assessment within a statistics and data analysis unit.
