Dataquest’s guided projects only come with guidelines. They do not make a certain method compulsory to follow. If you wish to add your own method of following through a step, you can/may do so. It is appreciated and encouraged! If you want to add something to the analysis, that is appreciated even more.
Still, in case you do wish to mark it as critical feedback, you can connect with the Dataquest team via Contact Us option and raise a ticket for the same.
