#### Standard Error Formula:

The SE formula depends upon the standard deviation and the number of sample values in the range. A sample's SE is described as the standard deviation of a sample divided by √n.

**Standard Error of Sample Means:**
It 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). It is commonly used in computing measures like confidence intervals and margins of error. Use this online standard error (SE) calculator to find the error value for the given set of values.

### Standard Error 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**
