# Average Rating Calculator

The average rating calculator takes a number of votes for each rating (1 star, 2 stars, 3 stars, 4 stars, 5 stars) and gives you the mean rating. This is an example of taking the weighted average, where the number of votes for each category are weighted by their score (i.e., 3 votes for 5 stars have a weight of 15, 6 votes for 4 stars have a weight of 24 etc.). An example of non-typical usage of our 5 star rating calculator would be when you have a certain number of 1-4 ratings and you want to find out how many new 5-star votes you need in order to achieve a certain mean rating.
