Marks out of 10 in a quick spelling quiz were 8, 8, 8, 6, 5, 10 and 10. What is the mode?
- 5
- 6
- 10
- 8
Answer: 8 — 8 appears 3 times — more than any other value — so the mode is 8. (10 appears only twice.)
A trotro carried 15, 11 and 10 passengers on 3 trips. What was the mean number of passengers per trip?
Answer: 12 — Add them: 15 + 11 + 10 = 36. There are 3 values, so 36 ÷ 3 = 12.
