Box Plots Worksheets for 9th Grade
Create and interpret box-and-whisker plots.
About Box Plots
Statistics teaches students to collect, display, and analyze data to draw meaningful conclusions. Students calculate measures of central tendency (mean, median, mode) and spread (range, IQR, standard deviation), construct and interpret box plots and histograms, and develop the vocabulary to describe data distributions. Statistical reasoning is an essential skill in the modern information age.
Box plots provide a compact visual summary of a distribution that shows center, spread, and outliers simultaneously. They are widely used in scientific and business reporting and are the standard display for comparing two groups in introductory statistics.
What Your Child Will Learn
- Construct a box plot using the five-number summary (min, Q1, median, Q3, max)
- Interpret the spread and skewness of data from a box plot
- Compare two distributions using side-by-side box plots
- Identify outliers on a box plot using whisker length and individual data points
- Extract the five-number summary from a given box plot diagram
Worksheets by Difficulty
Start with Easy worksheets to build confidence, then progress to Medium and Hard as your student masters each level.
Understanding the Difficulty Levels
Worksheets 1-3 are Easy level — designed to build confidence with simpler numbers and straightforward problem types. Great for introducing the concept or reviewing basics.
Worksheets 4-7 are Medium level — offering a moderate challenge with larger numbers, varied question types, and more problems per worksheet.
Worksheets 8-10 are Hard level — featuring the most challenging problems including multi-step questions, missing values, and real-world applications.
Tips for Parents & Teachers
Have your student calculate the mean, median, and mode of something they care about: sports scores, temperatures, or video game times.
Discuss why mean and median can be different — a few very high or very low values pull the mean but not the median.
Standard deviation sounds intimidating but just means "how far from the mean, on average" — normalize the concept with intuitive examples.
Practice reading box plots together using real data — sports statistics, weather data, and health data are all available online.
