Chapter 10 Flashcards
One way designs
1 IV, at least two conditions
what is required to qualify an experiment?
at least two condtions
between-subject designs
IV manipulated across groups of participants
within-subjects designs
participants are exposed to each level of the IV
factorial designs
at least two IV, each must still have at least two levels, 2x2
mixed factorial design
participants are randomly assigned to only one levle of some IVs but receive every level of other IVs
factorial nomenclature
use AxBxC to denote # of IV and # of levels/conditions of each IV
for # of IV
count the terms being multiplied ABC=3
for # of levels
look at actual number 2x2x2, then A=2, B=2, C=2
total condiitons
multiply together, 2x2x2=8 conditions
main effects
the effect of a single variable while ignoring the other
how to determine main effects
depending on how many IVs there are, 2x2-two possible main efffects
interaction
the effect of one variable depends upon the level of the other variable, if 2x2-one possible interaction
parallel lines
no interaction
intersect lines
interaction
