Correlation Tests One-Sample Test For Rho(0)

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 = Rho 0.

Hypotheses

The following hypotheses may be tested:

CT-Rho=0 Hyp

Where Rho is the true population correlation from which the sample was drawn.

Assumptions

  1. The sample has been randomly drawn from a bivariate (two-dimensional) population (Critical)
  2. The population may be modeled with a bivariate normal distribution (Not Critical, if unimodal)
  3. The correlation tested represents the degree to which a linear relationship exists between the two variables (Critical)

Test Statistics

CT - Rho=0

Where t has n-2 df.

Output

CT-Rho=0 Output

Note

The p-value is flagged with an asterisk (*) when p <= alpha.
