 # Fisher Transformation 0.75

<-- Enter r or z

Given a sample correlation coefficient (r) = 0.75, calculate the Fisher Transformation

z = ½Ln(a) where a is denoted below:
 1 + r 1 - r

## Calculate a:

 a  = 1 + 0.75 1 - 0.75

 a  = 1.75 0.25

a = 7

## Calculate z:

z = ½Ln(7)
z = ½(1.9459101490553)

## Excel or Google Sheets formula:

=FISHER(0.75)

z = 0.97295507452766
