How does the mean work?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The mean (average) is calculated by: Mean = Sum of all values ÷ Number of values
Formula: μ = (x₁ + x₂ + ... + x_n) / n
Steps:
- Add all numbers in the dataset
- Count how many numbers there are
- Divide the sum by the count
The mean represents the central tendency of data.
