   Question

   Below is the causal model in a mediation analysis schematically shown.
   What is the best description of the indirect effect in a mediation analysis?

   

   
   
   1. TRUE: The indirect effect is the effect of X on Y that proceeds through the mediator (mediating variable).
   2. FALSE: The indirect effect is the effect of X on Y controlled for the effect of mediator (mediating variable) on Y.
   3. FALSE: The indirect effect is the effect of mediator (mediating variable) on Y, controlled for the effect of X on Y.
   4. FALSE: The indirect effect is the summation of the effect of mediator (mediating variable) on Y and of the effect of X on Y.
   
   

   Solution

   concerning I: total 181/620=0.29 , thus 29% total yes.
   For France this would be 0.29*160=46.7.
   Thus 56 (counted) is more than expected .
   Thus I is true Concerning II: for the Netherlands: 0,29*150=43,5 to be expected if country and cannabis use is independent.
   Thus 36 is less than expected.
   Thus II is not true.
