Key idea: Mode — the most frequent value
**Mode** = the observation that occurs the most times.
- **Unimodal**: 2, 3, 4, 4, 5, 6 → mode = 4.
- **Bimodal**: 1, 2, 2, 3, 3, 4 → modes 2 and 3.
- **No mode**: 1, 2, 3, 4 (each appears once — sometimes considered 'no mode').
For a frequency table, the mode is the value with the HIGHEST frequency.
Mode is useful for categorical data (most popular colour, most common shoe size). Mean and median don't apply there.
