Using Correlations to Study the Association between Motor Vehicles Sales and Fuel Efficiency

In order to increase sales, motor vehicle design engineers want to focus their attention on aspects of the vehicle that are important to customers--for example, how important is fuel efficiency with respect to sales? One way to measure this is to compute the correlation between past sales and fuel efficiency.

Information concerning various makes of motor vehicles is collected in car_sales.sav. See the topic Sample Files for more information. Use Bivariate Correlations to measure the importance of fuel efficiency to the salability of a motor vehicle.
