Document Summary

Within-subjects designs: order effects and counterbalancing . // Controlling for the effects of bias: experimenter bias, subject bias. Anxiety level would be called the matching variable. Random assignment works very well with large samples. Example: you have the sat scores for 12 students: 480, 550, 490, 520, 670, 600, 590, 580, 550, 460, 610, 700. 101 group 1 115 group 2. Iq 101 group 2 114 group 1. If you have a study comparing two conditions and you want to test 20 people in condition 1, (cid:455)ou"ll (cid:374)eed to (cid:396)e(cid:272)(cid:396)uit (cid:1008)(cid:1004) people fo(cid:396) a (cid:271)et(cid:449)ee(cid:374)-subjects study but only 20 for a within-subjects study. Muller-lyer line illusions: horizontal, 45 degrees left, 45 degrees right, vertical. Advantages: require fewer participants, eliminate the equivalent-groups problem, each participant serves as their own control. Could be due to golf ball 2 being better (the brand being better, which is the hypothesis), or the golfers 6,7,8,9,10 could just be better.
