What is a hypothesis?
Answer
Formulate hypothesis:
1) X –> Y
2) X –> A –> Y
3) X –> B –> Y, conditional on A
Are the hypothesis supported?
H1 = yes
H2 = yes
H3 = uncertainty, no statistical significant measure of mediation -> comes down to decision making
Which effect is strongest?
Hard to say without standardizing all the effects
Another problem: highly controlled estimates
Can we say which mediator is stronger?
Sequence doesn’t allow for answering the question, no chance for choice mediator
also the nature of the hypothesis does not really allow it
Interpret coefficient of father’s education in model 3
How to interpret a coefficient?
be clear about
1) units
2) what is modelled, i.e. the mean
3) controls
Interpret p-value of father’s education in model 3
If the 0 hypothesis is true, ergo no effect in the population, a repeated 7.8% of samples you could draw at rondom from the population would produce a test statistic as large as ours.
