Homework 2Way ANOVA (Supplemental) . To test to see if cell phones cause more distraction and therefore more accidents researchers set up a driving course and had research participants drive the course while either talking on a cell phone. talking with a passenger, or listening to the radio. Researchers also thought that driving experience may influence the results, so they divided participants into those who have driven more than 10 years, and those who have driven less than 10 years. Driving errors were recorded for each participant. Test to see if there are differences in accidents under all of these conditions.

To test the effect of experience, calculated F=17.47, P=0.0006 which is < 0.05 .The effect of experience is significant.
To test the effect of Driving condition, calculated F=14.13, P=0.0002 which is < 0.05 .The effect of Driving condition is significant.
To test the effect of interaction, calculated F=3.84, P=0.0409 which is < 0.05 .The effect of interaction is significant.
