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
