Document Summary

Psyc 201 - lecture 7 - factorial designs. Designs in which two or more ivs examined. Level of each iv crossed such that it is combined w/ each level of other iv or variables in study. Provides more info to researcher & has several advantages over single-factor designs. Most basic factorial design - e. g. 2x2 design. Number of numbers indicates how many variables there are & value of each number indicates how many levels there are in variable. Indiv cells w/i factorial design typically described by name. Components of factorial design can be identified alphanumerically. Order of how variables in design presented can be mixed up but number of levels of each variable must remain the same. As more factors added in between-subjects experiment, number of participants required increases. If researcher wants to examine possible nonlinear effect in iv, researcher needs at least. Researcher can uncover possible main effects & interactions.
