Use JASP to open the PSYCH200 Vehicle Data.jasp data set. This data file contains information about the price, horsepower, and mileage estimates for over 400 different cars. Spend a minute looking at the data file and the variables so that you understand how the information is coded in the file. Importantly, note which values are listed as nominal values and which values are scale values. For the nominal values like SportsCar, SUV, and Wagon, you can think of the 1s and 0s as "Yes" and "No", respectively. So if a vehicle has a 1 in the SportsCar column, that means that yes, this vehicle is categorized as a sports car. If it has a 0 in that column, then it is not a sports car.
