No. Each question has 4 options and there’s no timer, so you can work at your own pace.

Can I choose an easier or harder version?

Yes. You can select the difficulty and the number of questions before starting; Mixed includes a balanced range.

What mistakes does this quiz help prevent?

It targets common errors like not sorting for the median, mishandling even counts, and choosing mean when outliers skew results.

About this quiz

What you’ll practice

Mean, median, and mode show up everywhere in descriptive statistics, but small mistakes can throw off your answer. This quiz helps you get fluent at computing each measure and explaining what it represents in plain language.

Expect a mix of straightforward number sets and interpretation questions where you decide which measure of center fits best.

Quiz format and difficulty

Every question has 4 options and there’s no timer, so you can focus on accuracy and reasoning. Choose your preferred question count and difficulty before you start—Mixed mode blends easy wins with tougher, more concept-heavy items to keep progress steady.

Common pitfalls to avoid

Forgetting to sort the data before finding the median
Using the wrong median rule for even-sized datasets (average the two middle values)
Mixing up mean vs. median when outliers are present
Missing that a dataset can have more than one mode (or no mode)
Rounding too early and drifting from the correct mean

How scoring stays balanced

Difficulty is balanced by combining quick-calculation prompts with “choose the best measure” scenarios and a few questions that test definitions and edge cases. You’ll see repeated patterns often enough to learn them, but with varied numbers so you can’t rely on memorization alone.
