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:
=FISHER(-0.5)
What is the Answer?
z = -0.54930614433405
