pdf Stem-And-Leaf Plot - Mean, Median, Mode and Range

This worksheet focuses on interpreting stem-and-leaf plots and using them to calculate measures of center and spread. Students are given two complete stem-and-leaf plots and must analyze the data directly from the visual representation rather than constructing the plot themselves.

In the first scenario, students examine quiz scores from a science class and determine the range, median, mode, mean (rounded to the nearest tenth), and the difference between the mean and median. In the second scenario, students analyze movie ratings collected from 20 reviewers and calculate the mean, median, mode, and range. A higher-level reasoning question asks students to determine which statistical measure would change if one of the highest data points were removed, strengthening conceptual understanding of how outliers affect data.

Because students must extract values from a visual display and perform accurate calculations, this resource reinforces both data interpretation skills and procedural fluency. It works well as independent practice, homework, review, or formative assessment within a statistics and data analysis unit.
