The different steps are describe hurriedly in the instructions, so it is hard to understand what it is we are supposed to compare and what we are supposed to learn exactly in this optional lab exercise. Same is true of the video preceding the lab.

Instructions as written lead to an error on account of one of the columns in the table you create to train your model is populated entirely by null values. To bypass, you need to omit the column mentioned in the thrown error by adding it to your EXCEPT in the step where you create the table.
