Find the average, the middle and the most common value — with steps.
Mean, median, mode and range games
Mean, median, mode and range
| Mean (average) | Add all values and divide by how many there are. 4, 6, 8 → 18 ÷ 3 = 6 |
|---|---|
| Median | Put the values in order; the middle one. Even count → average of the two middle values. 3, 5, 9, 11 → (5 + 9) ÷ 2 = 7 |
| Mode | The value that comes most often. 2, 3, 3, 7 → 3 |
| Range | Highest − lowest. 4, 9, 15 → 11 |
Empirical relation (Class 10): Mode ≈ 3 Median − 2 Mean.
For Class 6 to 10 (data handling and statistics). All answers are computed by a program.
