10. dteemrine from the graph, whether a study shows a three-way interaction: interpret key words that indicate factorial design, interpret keywords in popular press articles that indicate a factorial design. >within-groups design (everyone was subjected to both ivs) >asked participants to talk on hands-free cell and no cell while on driving simulator. >results showed that there was a difference between the two cell phone conditions. Took longer to brake when they were on the cell phone vs. not on phone. >to test this question > add another iv (old vs young driver) >interaction effects is of interest when you add another iv. Cell phone use (on cell phone vs. not on phone) x age (old vs. young driver) 2 x 2 factorial design (2 levels on each iv. We conduct a 2 (cell phone use: on cell phone vs. not on cell phone) x 2 (age: old vs. young driver) facotrial design. Independent variables are crossed > crossed factorial design.
