Question 1 of 1
1. Question
Data File: ANOVA.MTW
Situation:A safety analyst wants to compare how well drivers drive on three types of roads: paved, gravel, and dirt. To measure driving performance, the analyst records the time in seconds that each driver uses to make steering corrections on each type of road.
All other variables (vehicle type, speed, tires, tire air pressure, etc.) are held constant. Use the “ANOVA.MTW” data file to perform an ANOVA test to determine which road surface type yields the best and worst correction times.
Question:
Is there a statistical difference between the “road surface type” correction times?
