Averages: Practice Paper
A school-style paper: 10 questions in 15 minutes on the mean, the median and the mode, outliers and which average to use. One asks you to find a mistake. Every answer has a worked solution that names the usual slip.

Before you start
- It runs like an online exam: one question at a time, with a palette showing what you have answered, skipped or marked for review.
- The clock starts when you press Begin the test, after you have read the instructions, and keeps running even if you reload or leave. At zero, your saved answers are submitted.
- Leaving the test window is recorded, and your teacher can see it.
- Your score, the answers and the explanations show when you finish, with where you stand among everyone who has taken it.
