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)
z = -0.54930614433405

##### Excel or Google Sheets formula:

z = -0.54930614433405
