*Fisher Transformation is used  to test the hypothesis of two correlations.

*Fisher Transformation is used  to test the hypothesis of two correlations.

*It is mainly associated with the Pearson Product-Moment Correlation coefficient for bi-variate normal observations.

*In <math>FISHER(number)</math>, <math>number</math> is the value which ranges between -1 to +1.  

*In <math>FISHER(Number)</math>, <math>Number</math> is the value which ranges between -1 to +1.  

*The transformation is defined by : <math>z=\frac{1}{2} ln(1+\frac{x}{1-x})= arctanh(x)</math>

*The transformation is defined by : <math>z=\frac{1}{2} ln(1+\frac{x}{1-x})= arctanh(x)</math>

where <math>ln</math> is the natural logarithm function and <math>arctanh</math> is the Inverse Hyperbolic function.
