WebbThe population standard deviation formula is given as: σ = 1 N ∑ i = 1 N ( X i − μ) 2 Here, σ = Population standard deviation N = Number of observations in population Xi = ith … WebbThe covariance of two variables divided by the product of their standard deviations gives Pearson’s correlation coefficient. It is usually represented by ρ (rho). ρ (X,Y) = cov (X,Y) / σX.σY. Here cov is the covariance. σX is the standard deviation of X …
