The FISHER function returns the Fisher transformation at x. This transformation produces a function that is normally distributed rather than skewed. Use this function to perform hypothesis testing on the correlation coefficient.

FISHER takes 1 required argument and no optional arguments:

Syntax: FISHER(x)

#1)
Using the FISHER function:
#2)
The arguments for the FISHER function are:
Argument Required? Description
x Required A numeric value for which you want the transformation.
#3)
A couple things:
If x is nonnumeric, FISHER returns the #VALUE! error value.
If x ≤ -1 or if x ≥ 1, FISHER returns the #NUM! error value.

Summary

The FISHER function returns the Fisher transformation at x. This transformation produces a function that is normally distributed rather than skewed. Use this function to perform hypothesis testing on the correlation coefficient.
