multiple independent variable experiments Flashcards
factorial designs are for more than:
one independent variable
in factorial designs, each variable cane have:
independent groups or correlated groups
if all independent variables have independent groups, then the design is called:
a between subjects factorial design
if all IVs have correlated groups, then the design is called:
a within subjects factorial design
if at least one IV has independent groups and at least one IV has correlated groups, then the design is a:
mixed assignment factorial design
main effect:
the effect of one IV in a factorial design
interaction:
the joint effect of multiple IVs (where the effect of one depends on the other)
factorial design example:
2 IVs interaction: AxB
3 IVs interaction A B and C: AxB, BxC, AxC, AxBxC
