Question 16

Experiment 4

A marketing firm wants to determine what automobile features are most likely to influence car buyers to want to purchase the car. In particular, they want to know whether car buyers are more swayed by a smoother ride or improved interior vs. the original design of the car. They recruit 10 participants to test drive all three different versions of the car: the original design, smoother ride, and improved interior. After test driving each version of the car, they rate their likelihood/probability of purchasing the car on 0-100% scale.
