Mean (Average)
Mean (Average) is the sum of all numbers divided by the count: Mean = Sum / Count
Median is the middle value when numbers are sorted. If there’s an even count, it’s the average of the two middle values.
Mode is the number that appears most frequently. A set can have no mode, one mode, or multiple modes.
For example, given the numbers 3, 7, 7, 2, 9:
- Mean = (3 + 7 + 7 + 2 + 9) / 5 = 5.6
- Median (sorted: 2, 3, 7, 7, 9) = 7
- Mode = 7 (appears twice)
