Median & mode

Median: sort the values; the middle one. If count is even, take the average of the two middle.

Mode: the value that appears MOST often. A set can have no mode, one mode, or many modes.

Median isn't pulled by extreme outliers the way mean is — that's often more useful.

Example
Data: 3, 5, 7, 9, 11.
Median = 7 (middle of 5 sorted values).
Data: 2, 2, 3, 5, 5, 5, 8 → Mode = 5 (appears most).
💡 Tip:Mode is best for 'most popular' (sizes, colours, choices).
