This Grade 9 mathematics worksheet gives students structured practice creating and interpreting box-and-whisker plots. Across nine items, students order the five construction steps, identify the first, second, and third quartiles from a plotted display, locate the third quartile with a hotspot, determine the percentage of data in a quartile interval, calculate the interquartile range, compare medians for two cities, and complete a dropdown item about finding quartiles from divided data sets. The mix of ordering, multiple-choice, hotspot, and dropdown questions checks both procedural understanding and visual data interpretation. Use it for guided practice, independent review, or a formative check after introducing five-number summaries and box plots. Students work with values such as Q1 = 90, median = 100, and Q3 = 140, then connect those positions to percentages and spread. This free printable worksheet includes a complete answer key, making it practical for Grade 9 math instruction, homework, or assessment preparation.

FAQs

What does this Box and Whisker Plots worksheet help Grade 9 students learn?

This worksheet helps Grade 9 students sequence the steps for creating a box-and-whisker plot and interpret quartile positions on a plotted display. Its nine items ask students to identify Q1, the median, and Q3; locate Q3 with a hotspot; determine the percentage between values such as 40 and 90; calculate the interquartile range; and compare medians.

How can I use this worksheet to teach students to create and interpret box-and-whisker plots?

Begin with the ordering item to have students reconstruct the five-step process: order the data, find the key values, draw the number line, create the box, and mark the median. Then use the plotted-display questions to model how Q1, the median, and Q3 are read from a box plot before asking students to explain why the interval from 40 to 90 represents 25% of the data. Finish by discussing how subtracting Q1 from Q3 gives the interquartile range and how median positions support comparisons between cities.

What mistakes should I watch for when students complete this box-and-whisker plot worksheet?

Watch for students reversing Q1 and Q3, selecting the box edge instead of the median line, or choosing the wrong hotspot when locating the third quartile. Students may also calculate the interquartile range from the wrong values; this worksheet expects Q3 − Q1, or 140 − 90 = 50. In the percentage item, check that students recognize the span from the minimum value of 40 to Q1 at 90 represents 25% of the data.

How do I assign and grade this Box and Whisker Plots worksheet?

The worksheet is available as a printable PDF and as a digital quiz on Wayground, so you can download it for paper practice or assign the interactive version. It includes a complete answer key for checking the ordering, multiple-choice, hotspot, and dropdown responses. Printable submissions can also be graded by scanning student work with the Wayground for Teachers app.

How can I differentiate this box-and-whisker plot worksheet for my students?

Under the worksheet’s Advanced Settings, adjust font spacing or choose a larger font size to make the ordering and dropdown prompts easier to read alongside the box-plot visuals. You can also enable a dyslexia-friendly font or translate the worksheet into another language without changing its quartile, median, or interquartile-range questions.
