Calculation path
Estimate the standard error of a sample mean from sample spread and sample size. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
Calculation path
SE = s / sqrt(n)
What you receive
What you receive
- Standard error from the stated equation
- A symbolic formula plus substituted working with your values
- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
The observations should support the sampling assumptions used for the mean.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
