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.
Consider a set of data 1,3,5,7
The mean of the data is 4.
The Standard deviation SD is 2.58199
To find SE , 2.58199 / √4
= 1. 29099
Hence the SE of 1,3,5,7 is 1. 29099
