Standard Error Calculator

Standard Error Calculator to calculate the standard error of a set of numbers. The standard error formula is shown below on how to calculate the standard error.

What does the standard error mean?

The standard error of mean or standard error is a mathematics tool used in statistics to measure the error of a sample data.

How to calculate the standard error?

To calculate the standard error, we need to use the standard error formula.
SE = s /√n, where

s = standard deviation,
n = the size of the sample

To calculate the standard deviation, we use the standard deviation formula.
Sample Variance =

Standard Deviation = S = √Sample Variance, where

s² = sample variance
s = standard deviation
x1, ..., xN = the sample data set
x̄ = mean value of the sample data set
N = size of the sample data set
