Question 7

simple main effect

Answer 7

When we have a significant interaction,
we want to examine what is happening
at each level of the IV

The results are analyzed and described
as if we had separate experiments at
each level of the other independent
variable (i.e. the moderator)!

Question 8

key concepts

Answer 8

The effect of one IV on the DV within a single level of
the second IV (the moderator).

Always report the full set
- (in this case, both because there are two levels of the IV).
-What is the effect of one IV at each level of the other IV?

Decide on one way only to split the data.
Split by IV1
OR
Split by IV2
