Scaling parts of a dataset
In previous videos, you've used the QuantileTransformer on the full dataset. In this exercise, you will practice scaling only parts of a dataset. The reason for doing this is that the stocks datasets have numerically-encoded categorical features (day_of_week, day, month) that would have been incorrectly scaled if you used QuantileTransformer on the full dataset.
The transformer has been imported from sklearn along with the apple stocks dataset with the extra features.
