Question

In the table below,the pattern of results indicates: $\begin{array}{cccc} 
& & \text { Independent Variable A } \
&  & \text { A1 } & \text { A2 } \
&\text { B1 }  & 15 & 15 \
\text { Independent Variable B }&&\
& \text { B2 } & 7 & 7
\end{array}$

A) an important A main effect
B) an important B main effect
C) important A and B main effects
D) an important interaction
E) interaction and a main effect for A

Quizplus · Accepted Answer

The results show that the values change significantly between levels of Independent Variable B (from 15 to 7), but not between levels of Independent Variable A (both A1 and A2 have the same values at each level of B). This indicates a main effect for B, as the outcome is consistently different across the levels of B, regardless of the level of A. There is no interaction because the pattern of results is parallel (the difference between A1 and A2 is consistent across levels of B), and there is no main effect for A because the change across A1 and A2 does not vary.
