Quizzes
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.
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.
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.

Interesting facts
The “normal distribution” is often called a bell curve, but many real datasets are skewed, making median and IQR more reliable than mean and range. Also, a single outlier can dramatically change the mean, while the median may barely move.
