## 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
