INTERPRETING BOX PLOTS - SHEET 2 - Practice statements and answers

Oct 22, 2026

Worksheets for interpreting box plots, covering two monthly datasets: books read by a class of students and meals served each day at a restaurant. Students evaluate seven statements per box plot as true, false, or unknown, using key features such as the median, minimum, maximum, range, skew direction, and interquartile range. A corresponding answers section provides the correctness of each statement and short arithmetic or interpretation notes to justify the outcomes.

FAQs

How do you decide whether a statement about a box plot is true, false, or unknown?

Compare the statement with box-plot features such as the median line, whisker endpoints (minimum and maximum), and the box edges (quartiles). If the plot does not provide enough information for the claim, mark it as unknown.

What does the interquartile range represent in these questions?

It is the difference between the upper and lower quartiles (the height of the box). In the answers, it is computed using the quartile values shown by the box edges.

How can you tell whether the data is skewed left or right from the box plot?

Use the relative lengths of the whiskers and the position of the median within the box. The worksheet’s answers label skewness based on whether the tail extends farther to the left or the right.
