Numerical and Categorical Columns

Hello Fellow Students and Instructors,

I have submitted the assignment successfully but I still have a confusion regarding the Numerical Columns and Categorical Columns.

Some columns like ‘MSSubClass’, ‘OverallQual’, ‘OverallCond’ etc are treated as Numerical columns while training the model as they are being represented with numerical values in the input data. But these numerical values actually represent different classes as described in the ‘data_description.txt’ and hence according to my understanding should be considered as Categorical columns. Isn’t it ?

Would love to have point of view of others and the feedback from the course instructors would be great.

Thankyou
