Fisher's z transformation calculator
WebMar 7, 2024 · The sampling distribution of Pearson's r is not normally distributed. Fisher developed a transformation now called "Fisher's z-transformation" that converts Pearson's r to the normally distributed variable z. The formula for the transformation is: z_r = tanh^{-1}(r) = \frac{1}{2}log≤ft ( \frac{1+r}{1-r}\right ) Value. z value corresponding to ...

FISHER TRANSFORMATION Fisher developed a transformation of r that tends to become normal quickly as N increases. It is called the r to z transformation. We use it to conduct tests of the correlation coefficient and calculate the confidence interval.
