Question 3

similarities and differences between mediation and moderation

Answer 3

Similarities:
a. In their most simplest form 
    mediation and moderations 
    both involves three 
    variables.
b. Both mediation and 
    moderations can be done 
    with a regression analysis.
c. Both mediation and 
    moderation look at the 
    impact of a third variable on 
    a 2-varaibles relationship 
    (IV-DV).

Differences:
a. Moderation involves an 
    interaction term.
b. Moderation does not 
    identify causality (i.e. not a 
    causal model)
c. IV and ModV do not have to 
   be correlated in order to find 
   a significant moderation.
d. Graphing is essential in a 
    moderation analysis.

Question 4

Mediation is about the

Answer 4

Mediation is about the mechanism between the IV-DV (HOW)

• We use mediation analysis to 
  identify one possible 
  mechanism through which 
  the IV predicts the DV.
• We are not comparing 
  subgroups within the data in 
  a mediation analysis.
• Finding mediations are 
  common i.e. 60-80% of the 
  time with social variables 
  (rather than cognitive 
  variables).

Question 5

Moderation is about …

Answer 5

Moderation is about (WHO) do subgroups differ in the strength of the IV-DV relationship?
• Moderations are rare to find,
only 10-15% of the time but
they are very illuminating.
