Standard Error Calculator

Standard Error is the sampling distribution of a statistic, commonly of a mean value. It can also be referred as the estimation of the standard deviation. If the sample mean varies from the actual mean of the population, the variation is called as standard error (SE). The standard deviation of a sample divided by √n is the SE of the sample. This Standard Error calculator helps you to find the SE for the given range of values.

Formula:

Standard Error of Sample Means Where, SE = Standard Error s = Standard Deviation n = Size (Number of Observations) of the Sample.

Example:

Consider a set of data 1,3,5,7

Step 1 :

The mean of the data is 4.

Step 2 :

The Standard deviation SD is 2.58199

Step 3 :

To find SE , 2.58199 / √4
= 1. 29099
Hence the SE of 1,3,5,7 is 1. 29099
