An interaction can be best characterized as:

a) When two IVs affect one another

b) When the effect of an IV on a DV is conditional upon the level of another IV

c) When the effect of an IV on a DV is unconditional upon the level of another IV

d) The average effect of an IV on the DV, ignoring the other IV

e) When the DV behaves differently for different IVs

4. The SSinteraction can be found by:

1. SStotal - SSbetween
2. SStotal - (SScol + SSrow)
3. SSbetween - (SSwithin + SSrow)
4. SSwithin - (SScol + SSrow)
5. SSbetween - (SScol + SSrow)
