pdf Box Blot Creation & Analysis

This box-and-whisker plot worksheet gives students practice constructing and analyzing five-number summaries and box plots. Students work with three different forms of information: an unsorted raw data set, a completed box-and-whisker plot, and a given five-number summary. They identify quartiles, calculate interquartile range, construct box plots, and interpret the variation shown within different sections of a distribution.

The activity connects numerical summaries with graphical representations of data. Students sort raw values, determine the minimum, first quartile, median, third quartile, and maximum, and use those values to construct an accurate box plot. They also read values from an existing graph, compare the lengths of quartile intervals, and support conclusions about variation with numerical evidence.

This resource works well for instruction, guided practice, independent practice, review, intervention, or assessment. It moves students beyond simply drawing box plots by requiring them to interpret the median and analyze how data are distributed within each quartile. The worksheet prepares students for later work involving measures of variability, comparisons of distributions, and statistical reasoning.
