Question: A researcher measures three variables, X , Y , and Z for each individual in a sample of n = 25. The Pearson correlations for this sample are r XY = 0.8, r XZ = 0.6, and r YZ = 0.7.
- Find the partial correlation between X and Y , holding Z constant.
- Find the partial correlation between X and Z , holding Y constant. ( Hint : Simply switch the labels for the variables Y and Z to correspond with the labels in the equation.)
