Key idea: Mean — the 'fair share'
The **mean** is what each person would get if you redistributed everything evenly. Sum the values, divide by the count.
Example: marks 8, 6, 7, 9, 10. Sum = 40. Count = 5. Mean = 40 ÷ 5 = 8.
Mean is the most common 'average' but it can be pulled up or down by extreme values (one very high or very low number).
