The data you will use is in the file car_ads_fp.RDataprovided in Blackboard (this is not the same data used in lecture 12). When you have finished collecting, cleaning, and exploring the data, the subset you should have when you move to the analysis stage will have six variables and 2380 observations (rows). Of the six variables, three are number-type, and three are object- type. If your data does not have these characteristics, it's likely that either you didn't sufficiently clean the data or, somewhere along the way, you did not inspect what you expected.
