11th Grade Box and Whisker Plot Quizzes

Start with an ordered data set and have students calculate the minimum, first quartile, median, third quartile, and maximum before drawing the plot. Then connect each part of the graph to the five-number summary and use paired plots to discuss differences in center, spread, and possible outliers.

Use a progression of three task types: construct a plot from raw data, recover statistical values from a completed plot, and compare two distributions. For example, students might decide which of two groups has the higher median and which has the larger interquartile range, then support both conclusions with values from the graphs.

Common errors include finding quartiles before ordering the data, confusing the interquartile range with the full range, and treating whisker endpoints as outliers. Students may also describe one distribution as more variable without comparing its box width or overall spread.

Wayground quizzes are available as printable PDFs and digital formats, so teachers can assign a hosted digital quiz or distribute the same practice on paper. Every quiz includes a complete answer key, and paper submissions can be scanned or captured for grading with the Wayground for Teachers app.

This topic aligns with Common Core's emphasis on summarizing and comparing numerical distributions. It builds from calculating measures such as median and quartiles toward using differences in center and spread to compare populations or experimental groups.

Give students who need visual accessibility a version with larger text or wider font spacing. For digital work, reduced answer choices can make interpretation questions more manageable, while extended time helps students complete multi-step tasks such as ordering data and calculating quartiles. These accommodations can be assigned to individual students without changing the experience for the rest of the class.

These quizzes are designed for Grade 11 probability and statistics. At this level, students move beyond identifying parts of a box plot to constructing five-number summaries, analyzing outliers, and comparing distributions in context.
