Formula and methodology
Formula: Standard error = σ/√n; approximate 95% interval around μ = μ±1.96×standard error.
The sampling-scale term and a reference 95% interval are returned separately.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Population mean — minimum -1000000000; maximum 1000000000
- Population standard deviation — minimum 0; maximum 1000000000
- Sample size — minimum 1; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Population mean | 50 |
| Population standard deviation | 12 |
| Sample size | 36 |
Standard error =2; reference 95% interval =46.08 to53.92.
Assumptions and limits
- Standard deviation is nonnegative and sample size is a positive whole number.
- The sample mean is modeled by a normal approximation under the stated population assumptions.
- Finite-population correction, skew, dependence, bias, and unknown-parameter estimation are not modeled.
