STATS - chapter 1, in the beginning...

1. not just 'whether or if', but also 'how and when'

   • 'whether, if' answers the first part of research - if two variables are related
   • 'how, when' - how x affects y and when x affects y

2. mediation

   • X
     • Y
     • M
       • Y
   • mediation analysis - statistical approach to quantifying direct and indirect effects of X on Y
   • one or more intervening variables 'M' is located causally between X and Y
     • the mechanisms by which X effect Y
   • quantify and examine direct and indirect pathways through which ANTECEDENT X transmits effects on the CONSEQUENT Y

3. moderation

   • Y
     • X
       • • M
   • moderation analysis - statistical approach to uncover the boundary conditions between 2 variables
     • size of causal effect X has on Y

4. conditional indirect effect

5. conditional process analysis

   • used to describe the conditional nature of the mechanisms of how a variable transmits effects on another variable and providing testing hypothesis for these
