## How to Compute the Arithmetic Mean

### Formula

**Mean = (Sum of all values) / (Number of values)**

The arithmetic mean represents the central tendency of a dataset by distributing the total evenly across all observations. It is sensitive to extreme values, so outliers can shift the mean significantly.

计算示例

Find the mean of 10, 20, 30, 40, and 50.

  1. Sum all values: 10 + 20 + 30 + 40 + 50 = 150
  2. Count the values: 5
  3. Mean = 150 / 5 = 30
