First-Order Partial Correlations
For Three Intercorrelated Variables:

The logic and computational
details of partial correlation
are described in Subchapter 3a
of Concepts and Applications.

Given three overlapping correlation coefficients
   rXY    rXZ    and    rYZ
this page will calculate the first-order partial correlations
   rXY.Z    rXZ.Y   and   rYZ.X

To proceed, enter the values of rXY , rXZ , and rYZ into the designated cells below, then click the «Calculate» button. A negative value of r should be preceded by a minus sign: e.g., -.76. Do not enter a plus sign; all entered values are assumed to be positive unless preceded by "-". Values of r2 will calculated and entered automatically.

If you enter the value of N (providing N>6), the program will also calculate the values of t for the partial correlations (df=N3) along with the associated two-tailed probability values.

[Optional]  N =

1st Order Partial Correlations
P values are non-directional (two-tailed)
