A linear modeling project coded in R illustrating the difficulty of predicting outcomes with small data sets.
- Question: Do manual transmissions produce better mileage than automatics?
- Answer:When all physical aspects of vehicles are considered (i.e. gear ratio, weight , etc) there is no difference in mileage between manual and automatics.
- Challenges:This data set was small (<40 cars or samples) and therefore limited the conclusions that could be drawn. It is likely that with a larger data set manual transmissions would predict better mileage.
