SHOW ALL THE WORK AND CALCULATION STEP BY STEP 1.  a researcher measures three variables, X, Y, and Z for each individual in a sample of n=25.  The  Pearson correlation for this sample are  r xy =0.8,  r xz =0.6 and  r yz =0.7 a) find the partial correlation between X and Y holding Z constant  b) 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 bales in the equation.)  2. a) one set of 12 pairs of scores X and Y values produce a correlation of r=0.90. if SS Y =200 find the standard error of estimate for the regression line. b) a second set of 12 pairs of X and Y values produces of correlation of r=0.60. if SS Y =200 find the standard error of estimate for the regressions line.
