WebTests. When the null assumption is ρ 0 = 0, independent variables, and X and Y have bivariate normal distribution or the sample size is large, then you may use the t-test. When ρ 0 ≠ 0, the sample distribution will not be symmetrical, hence you can't use the t distribution. In this case, you should use the Fisher transformation to transform the distribution. WebDec 16, 2024 · The Correlation Coefficient is calculated by dividing the Covariance of x,y by the Standard deviation of x and y. Units of Cov (x,y) = (unit of x)* (unit of y) Units of the standard deviation of x = unit of x Units of the standard deviation of y = unit of y. So, unit of correlation coefficient = (unit of x)* (unit of y) / (unit of x) (unit of y)
