WebHow To Calculate Standard Deviation in R The standard deviation of a sample is one of the most commonly cited descriptive statistics, explaining the degree of spread around a sample’s central tendency (the mean or median). It is commonly included in a table of summary statistics as part of exploratory analysis.
