I haven’t been able to figure out what they are asking for:
“Calculate an average rating for each movie in our collection where English is an available language, the minimum imdb.rating is at least 1, the minimum imdb.votes is at least 1, and it was released in 1990 or after. You’ll be required to rescale (or normalize ) imdb.votes. The formula to rescale imdb.votes and calculate normalized_rating is included as a handout.”
The documents already contain the “average of the rating”. So why would I need to do rescale the votes? Given the handout, I can guess that they mean “the average of rating and normalized votes”. Is that it?
