Standard Error Calculator

A Standard Error Calculator is a statistical tool used to estimate the standard deviation or variability of a sample mean. It helps determine the precision and reliability of the sample mean as an estimate of the population mean.

Formula

The formula for calculating the standard error depends on the sample size and the standard deviation of the population.

The formula for the standard error is: Standard Error = (Standard Deviation of the Population) / √(Sample Size)

Example

For example, let’s say we have a sample of 100 individuals with a standard deviation of 5. By plugging these values into the formula, the standard error would be: Standard Error = 5 / √(100) = 5 / 10 = 0.5
