Suppose, you are given three variables X, Y and Z. The Pearson correlation coefficients for (X, Y), (Y, Z) and (X, Z) are C1, C2 & C3 respectively.
Now, you have added 2 in all values of X (i.enew values become X+2), subtracted 2 from all values of Y (i.e. new values are Y-2) and Z remains the same. The new coefficients for (X,Y), (Y,Z) and (X,Z) are given by D1, D2 & D3 respectively. How do the values of D1, D2 & D3 relate to C1, C2 & C3?
A) D1= C1, D2 < C2, D3 > C3
B) D1 = C1, D2 > C2, D3 > C3
C) D1 = C1, D2 > C2, D3 < C3
D) D1 = C1, D2 < C2, D3 < C3
E) D1 = C1, D2 = C2, D3 = C3
F) Cannot be determined
