Descriptive Statistics
Practice the core tools of descriptive statistics used to summarize and interpret data. These quizzes cover measures of center and spread, percentiles, and reading tables and charts so you can describe datasets clearly and accurately.
Quizzes
Mean, median, and mode basics
Build confidence with the three core measures of center: mean, median, and mode. You’ll practice quick calculations, choosing the right measure for a dataset, and interpreting what each one says about “typical” values. Great for students, refresher study, or anyone brushing up on descriptive statistics.
Range, IQR, and standard deviation
Test your understanding of spread with range, interquartile range (IQR), and standard deviation. You’ll work through quick calculations and interpretation questions, including choosing the best measure for a situation. Pick how many questions you want and the difficulty level, then practice at your own pace with no timer.
Reading box plots and histograms
Sharpen your ability to interpret box plots and histograms with real, exam-style visuals and scenarios. You’ll practice spotting center, spread, skewness, and outliers, then translating what you see into clear statistical statements. Choose your preferred question count and difficulty to match quick refreshers or deeper practice.

What you’ll practice
These Descriptive Statistics quizzes help you summarize datasets using the most common numerical measures and visual interpretations.
You’ll work with mean, median, mode, range, variance, standard deviation, quartiles, percentiles, and interpreting distributions from tables or graphs.
How the quizzes work
Each question has 4 answer options and there is no timer, so you can focus on accuracy and reasoning.
Difficulty and length vary across the set: you’ll see quicker definition-and-formula checks as well as longer, multi-step calculation and interpretation items.
Key skills covered
- Compute and compare measures of central tendency
- Calculate variance and standard deviation from data or summaries
- Use quartiles, IQR, and percentiles to describe spread and outliers
- Interpret histograms, box plots, and frequency tables
- Choose appropriate statistics for skewed vs. symmetric data
Quick context and facts
Descriptive statistics is the foundation of data analysis because it turns raw observations into interpretable summaries before you model or infer anything.
Many real-world dashboards rely heavily on descriptive measures (like medians and percentiles) because they are robust to outliers and easier to communicate than complex models.
