34 Plot the point whose polar coordinates are given. Then find the Cartesian coordinates of the point.
COMPLEX DESIGNS So far, we’ve discussed studies with just one IV. But many studies have more than 1. Sometimes, this can hide important findings! Example: » Hypothesis: Caucasian faces are easier to remember than Japanese faces. » IV: Race of face (2 levels: Caucasian and Japanese) » DV: Percentage of faces remembered So let's amend that hypothesis... » Hypothesis: Caucasian participants will remember Caucasian faces better than Japanese faces, but Japanese participants will remember Japanese faces more. » IVs: 1.

Race of Participant (Caucasian or Japanese) » DV: Percentage of faces remembered This is an example of an interaction between two IV’s. o The effect of one IV (race of face) is different
