The Correlation Test for Rho = 0 is used to test if a correlation exists between two variables. The correlation represents the degree to which a linear relationship exists between these two variables. If the desired test is for a specific correlation value, other then zero, see the Test for Correlation = .
The following hypotheses may be tested:
Where is the true population correlation from which the sample was drawn.
Where t has n-2 df.
The p-value is flagged with an asterisk (*) when p <= alpha.
