This calculator will compute the covariance between two variables x and y, given the pearson correlation coefficient for the two variables, and their standard deviations. Standard deviation in statistics, typically denoted by σ, is a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values in a set of data.
