Using
the Fisher r-to-z transformation, this page will calculate a value of z that can be applied to assess the significance of the difference between
| r, the correlation observed within a sample of size n
and
| rho, the correlation hypothesized to exist within the population of bivariate values from which the sample is randomly drawn.
| | |
If
r is greater than
rho, the resulting value of z will have a positive sign; if
r is smaller than
rho, the sign of z will be negative.
To perform the calculation, enter the relevant values into the designated cells, then click the 'Calculate' button.
