Learn how to calculate z scores in R with this step-by-step tutorial. Use R's powerful functions to standardize your data and analyze its distribution. Computing Z Scores in R Z-Score Transformation in R Transforming a Variable to Z-Score in R Calculating Z Scores in R Manually Given a distribution with mean $\overline{x}$ and standard deviation $s$, a location-scale transformation known as a Z-score will shift the distribution to have mean 0 and scale the spread to have standard deviation 1:
