I started an attempt at program comparison in my article Zipfian Academy versus Data Science Apprenticeship, comparing two apples, rather than comparing apples (stuff like our program, known as DSA) with oranges (Coursera) and lemons (university data science curricula).
But how would you create a universal ranking or score, that would simply put everything (apples, lemons, oranges...) in one bucket and rank them according to satisfaction and results. Results could be ROI. But in the case of our DSA, since cost = 0, ROI is infinite. So a better metric is needed to measure lift or yield or return.
The attributes I have in mind are:
Do you have other attributes in mind? Or a better solution to create these rankings?
