q |
When the true correlation coefficient is zero (H0:
r=0 and H1: r¹0)
|
|
|
|
|
Use Student-t to test
the significance of r
|
|
|
and n = N-2 degree of freedom
|
|
|
q |
When the true correlation coefficient is
not expected to be zero
|
|
|
We can not use a
symmetric normal distribution for the test.
|
|
|
We must use Fisher’s Z
transformation to convert the distribution of r
|
to a normal
distribution:
