Key idea: Mode — the most common
The **mode** is the value with the highest frequency. Count occurrences:
- 2, 3, 3, 5, 7 → mode = 3 (appears twice).
- 1, 1, 2, 2, 3 → two modes: 1 and 2 (bimodal).
- 1, 2, 3, 4, 5 → no mode (all distinct).
Mode is the only 'average' that works for non-numeric data (e.g. most common shoe colour).
- 2, 3, 3, 5, 7 → mode = 3 (appears twice).
