Answer key · Determine the mode and range of a data set
- 1.4 — 4 appears most often, so the mode is 4.
- 2.11 — 11 appears most often, so the mode is 11.
- 3.12 — 12 appears most often, so the mode is 12.
- 4.17 — The largest is 20 and the smallest is 3, so the range is 20 − 3 = 17.
- 5.15 — The largest is 19 and the smallest is 4, so the range is 19 − 4 = 15.
- 6.11 — The largest is 16 and the smallest is 5, so the range is 16 − 5 = 11.
- 7.11 — 11 appears 3 times — more than any other value — so the mode is 11.
- 8.2 — 2 appears 3 times — more than any other value — so the mode is 2.
- 9.7 — 7 appears 3 times — more than any other value — so the mode is 7.
