Standard Error for Estimated Mean
Use independent sample values estimate standard error of mean.
Your numbers
Standard-error value
Use consistent units. Result follow the assumptions wey you enter.
Compare scenarios
You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
Use SE = s/√n. s na sample standard deviation and n na di number of independent observations. Standard error dey describe how sample mean fit vary; e no be di spread of individual observations.
Use independent sample values estimate standard error of mean.
Example wey show the calculation
- Values wey you observe for the sample
- 10, 20, 30
- Standard-error value
- 5.7735026919
- Di sample standard deviation
- 10
- How many items the sample get
- 3
Where e fit work and limits
Use consistent units. Result follow the assumptions wey you enter.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
