Compute Variance and Standard Deviation of a value in R Programming – var() and sd() Function
var() function in R Language computes the sample variance of a vector. It is the measure of how much value is away from the mean value.
x : numeric vector
Example 1: Computing variance of a vector
Here in the above code, we took an example vector “x1” and calculated its variance.
sd() function is used to compute the standard deviation of given values in R. It is the square root of its variance.
Syntax: sd(x) Parameters: x: numeric vector
Example 1: Computing standard deviation of a vector
Here in the above code, we took an example vector “x2” and calculated its standard deviation.
