Hi all,
So I was running a Hierarchical multiple regression with 4 IVs in the first block, then 3 IVs in second block. the Model for the first block showed all IVs as statistically insignificant. But then, in the second block, one of the IVs then became stat sig with the introduction of the other 3 IVs (only 2 of which were stat sig themselves).
So I ran an moderation analysis and mediation analysis. No moderation. But mediation showed that one of the block 2 IVs mediated the original block 1 IVs effect on DV. But the mediation analyses suggested this was only partial mediation - the data showed a c prime route for effect on DV.
So my question is - HOW? How can the mediation analysis suggest a c prime pathway, when the HMR only had block 1 IV become stat sig AFTER introduction on block 2 IVs?
I hope someone can help.
