About this calculator
Overview
This mean calculator computes the arithmetic mean (average) of a list of numeric values.
When to use
Use it for descriptive statistics when the arithmetic average is the appropriate central-tendency measure.
Formula / method
Mean = (sum of values) / (count of values).
Worked example
Values 2, 4, 6, 8 → mean = 20 / 4 = 5.
Interpreting results
The mean is sensitive to outliers; consider median for skewed data.
Assumptions
- All listed values are included with equal weight.
- Count is at least 1.
Limitations
- Does not compute weighted mean unless a separate weighted tool is used.
