Formula and methodology
Formula: Mean=Σx/n; population variance=Σ(x−mean)²/n; standard deviation=√variance.
Location and spread summaries are reported from one explicitly parsed list using population denominators.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Data values — Enter 2 to 500 finite numbers separated by commas or spaces.
Worked example
| Input | Value |
|---|---|
| Data values | 4, 7, 7, 9, 13 |
Mean =8; median =7; range =9; population standard deviation ≈3.033.
Assumptions and limits
- The input contains 2 to 500 finite numeric values separated by commas or whitespace.
- Variance and standard deviation use the population denominator n.
- Sampling weights, missing values, measurement units, and inferential conclusions are not modeled.
