I have an average rating of all votes as well as the total number of votes for all episodes of the TV show Always Sunny. Is it mathematically sound to?:

1) multiply each average rating by the total votes cast for that episode

2) take the array of all those values and normalize it so the lowest is 0 and the highest is 10

3) use that new value as the actual rating

  • $\begingroup$ How is this different from your previous question? You do want to rank a set of movies, right? $\endgroup$

  • $\begingroup$ The previous question concerned discrete yes/no votes. This concerns a continuous 0-10 rating. To be perfectly clear, I don't want to actually "rank" anything. I just want to take into account the total number of votes somehow for each episode to produce a fairer rating. Like give 0-10 ratings with more votes more weight. I just used the term "rank aggregate" cause I thought that's what the official term for this is. $\endgroup$
