Correlation Probability Calculator

Creates the p value for a given correlation coefficient or the correlation coefficient (based on a specified sample size) for a user-specified value of p; also computes the Fisher z transformation for correlation coefficients.

Correlation

Element Name Description
Two-sided Select this option to perform a two-sided (two-tailed test); if this option is not selected, then a one-sided (one-tailed) test will be performed.
Type of computation Specifies the type of computation that you want to perform.
Sample size N Specifies the sample size (number of cases) for the computations.
Correlation r Specifies the Pearson product moment correlation coefficient (r).
p value Specifies the probability value p to compute the correlation coefficient r and the Fisher transformed coefficient z from the p value.
z Specifies the Fisher z value for the computation of the correlation coefficient from the Fisher z-transformed value.
