Answer key · Determine the mode and range of a data set
- 1.12 — 12 appears most often, so the mode is 12.
- 2.8 — 8 appears most often, so the mode is 8.
- 3.5 — 5 appears most often, so the mode is 5.
- 4.16 — The largest is 19 and the smallest is 3, so the range is 19 − 3 = 16.
- 5.17 — The largest is 18 and the smallest is 1, so the range is 18 − 1 = 17.
- 6.15 — The largest is 20 and the smallest is 5, so the range is 20 − 5 = 15.
- 7.14 — 14 appears 3 times — more than any other value — so the mode is 14.
- 8.7 — 7 appears 3 times — more than any other value — so the mode is 7.
- 9.11 — 11 appears 3 times — more than any other value — so the mode is 11.
