Mean, Median, Mode and Range -- Sorted Sets (Sets of 5 from 10 to ... - Free Printable

Let’s solve each set step by step. For every set, we’ll find:

- Mean = add all numbers, then divide by how many numbers there are.
- Median = put numbers in order (they already are), then pick the middle one. If even count, average the two middle ones.
- Mode = number that appears most often. If none repeat, say “no mode”.
- Range = biggest number minus smallest number.

We’ll go one by one.

1) {18, 18, 63, 63, 84}

- Mean: (18 + 18 + 63 + 63 + 84) = 246 → 246 ÷ 5 = 49.2
- Median: Middle of 5 numbers → 3rd number = 63
- Mode: 18 and 63 both appear twice → 18 and 63 (bimodal)
