Obtain the standard error of the mean

se_mean(x, na.rm = FALSE)

## Arguments

x |
a numeric vector |

na.rm |
a logical value indicating whether NA values should be stripped before the computation proceeds. |

## Value

a scalar equal to the standard error of the mean, computed as sd(x)/(sqrt(n)).

## Examples

x <- rnorm(100)
mean(x)

#> [1] 0.03102274

se_mean(x)

#> [1] 0.08982355
