Answer key · Determine the mode and range of a data set
- 1.1 — 1 appears most often, so the mode is 1.
- 2.12 — 12 appears most often, so the mode is 12.
- 3.7 — 7 appears most often, so the mode is 7.
- 4.15 — The largest is 20 and the smallest is 5, so the range is 20 − 5 = 15.
- 5.11 — The largest is 17 and the smallest is 6, so the range is 17 − 6 = 11.
- 6.15 — The largest is 20 and the smallest is 5, so the range is 20 − 5 = 15.
- 7.9 — 9 appears 3 times — more than any other value — so the mode is 9.
- 8.10 — 10 appears 3 times — more than any other value — so the mode is 10.
- 9.3 — 3 appears 3 times — more than any other value — so the mode is 3.
