Document Summary

Level of independent variable: 2+ different conditions/ groups of each variable e. g: drug iv includes conditions: low dose, medium dose and high dose (cid:0) different doses is level of iv each of. Has at least 2 ivs/ factors (cid:0) factors are not unlimited as the other design contain. Could study the effects of crowding and number of ppl at the same time. Note: - iv/ factors are assigned letters while levels of iv are assigned numerals. Three more ivs are hard to be interpreted, even seasoned researchers. Mixed factorial design: consists of between-subjects (independent design groups) and within-subjects (repeated measures) Between-subjects: participants will be assigned randomly to each of condition. Within-subjects: participants will be assigned randomly to all conditions. Main effects: measured changes in dv that are due to only one of the ivs (cid:0) one main effect for each iv.
