pdf Quiz - Box And Whisker Plots

This quiz assesses students’ understanding of box-and-whisker plots through two separate graphical data sets. Students analyze each box plot to determine Q1, Q3, median, range, interquartile range (IQR), minimum, and maximum values. In addition to calculating measures of spread, students must interpret quartile positions and determine which quartile contains specific values.

The first section focuses on identifying key components directly from a box-and-whisker plot, reinforcing recognition of quartiles and variability. The second section presents a real-world context involving math test scores, requiring students to interpret the distribution of 25 data points and reason about how values are grouped within quartiles.

Because students must interpret graphical representations rather than raw data sets, this resource strengthens conceptual understanding of how box plots summarize distributions. It works well as a summative quiz, formative assessment, review, or checkpoint within a statistics and data analysis unit.
