Variance in R (Example)
This article explains how to calculate the variance of numeric data with the var() function in the R programming language.
Example Data
my_values <- c(4, 1, 8, 5, 4, 4, 5, 6, 8, 1) # Create example values
Computation of Sample Variance in R (var Function)
We can compute the variance of our example data with the var function:
var(my_values) # Compute sample variance # 5.642857
Note that the var function is computing the sample variance and not the population variance.
