Answer key · Determine the mode and range of a data set
- 1.9 — 9 appears most often, so the mode is 9.
- 2.12 — 12 appears most often, so the mode is 12.
- 3.6 — 6 appears most often, so the mode is 6.
- 4.16 — The largest is 18 and the smallest is 2, so the range is 18 − 2 = 16.
- 5.13 — The largest is 19 and the smallest is 6, so the range is 19 − 6 = 13.
- 6.16 — The largest is 18 and the smallest is 2, so the range is 18 − 2 = 16.
- 7.6 — 6 appears 3 times — more than any other value — so the mode is 6.
- 8.6 — 6 appears 3 times — more than any other value — so the mode is 6.
- 9.6 — 6 appears 3 times — more than any other value — so the mode is 6.
