   Below is the causal model in a moderation analysis (idem: interaction) is shown schematically.
   What is the best description of the main question in a moderation analysis? 

   

   
   
   1. TRUE: To what extent does the direction and strength of the effect of a cause variable X on consequence variable Y depends on the value of variable Z?
   2. FALSE: What is the direction and strength of the effect of cause variable X on variable Z, controlled for the effect of Z on consequence variable Y?
   3. FALSE: To what extent does the effect of a cause variable X on consequence variable Y through the mediating variable Z?
   4. FALSE: To what extent does the value of cause variable X depend on the direction and strength of the effect of variable Z on consequence variable 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.
