Fisher Transformation -0.5

<-- Enter r or z
    
Given a sample correlation coefficient (r) = -0.5, calculate the Fisher Transformation

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

Calculate a:

a  =  1 + -0.5
  1 - -0.5

a  =  0.5
  1.5

a = 0.33333333333333

Calculate z:

z = ½Ln(0.33333333333333)
z = ½(-1.0986122886681)





Excel or Google Sheets formula:

=FISHER(-0.5)


What is the Answer?

z = -0.54930614433405
