Mean, Median & Mode — Definitions
Mean (Arithmetic Average)
x̄ = Σxᵢ / n — add all values and divide by count. Sensitive to outliers.
Median
Sort values. If n is odd: middle value. If n is even: average of the two middle values.
Robust to outliers; preferred for skewed distributions.
Mode
The value(s) that appear most often. Can be: no mode, unimodal, bimodal, or multimodal.
Range
Range = Max − Min. A simple spread measure.
Quick Example: 3, 7, 5, 13, 20, 23, 39, 23, 40, 23
| Measure | Value | How |
|---|---|---|
| Mean | 19.6 | (3+7+5+…+23) / 10 |
| Median | 21.5 | Sorted → (20+23)/2 |
| Mode | 23 | Appears 3 times |
| Range | 37 | 40 − 3 |
