5★ rating average returns an average rating based on the number of 1-5 ratings.

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.

You may also be interested in our average calculator, or in another example of a weighted average problem. Our college GPA calculator is perfect when you want to know what your current grade is, or what you need to do to achieve your desired GPA. When calculating this, grades are weighted based on the number of credits.
