PS395 Lecture 7: Mediation Test Notes
Document Summary
Why: through the (cid:862)hardy(cid:863) traits a(cid:271)ility to i(cid:374)(cid:272)rease self-esteem, it decreases how much discrimination is perceived. Paths (cid:271), (cid:272)": = b1x1 + b2x2: for path a, we find the slope of b1, how much do both x and m predict y, outcome. Path b comes from b1 = relationship between m and y, controlling for x. Path (cid:272)" = (cid:271)2 = relationship between x and y, controlling for m.
