# Standard Error in R (Example)

On this page, I’ll explain how to calculate the standard error in the R programming language.

## Example Data

We use the following numeric vector as example data:

x <- c(6, 8, 4, 3, 9, 3, 5, 1, 3, 2, 5, 2) # Create example vector |

x <- c(6, 8, 4, 3, 9, 3, 5, 1, 3, 2, 5, 2) # Create example vector

## Example: Computation of Standard Error in R

We can compute the standard error with a combination of the sd, sqrt and length functions:

sd(x) / sqrt(length(x)) # Compute standard error # 0.7084447 |

sd(x) / sqrt(length(x)) # Compute standard error # 0.7084447

The standard error of our example data is 0.7084447.
