## Average Rating Formula

The following equation can be used to calculate the average star rating given the total number of ratings at each level.

AR = 1*a+2*b+3*c+4*d+5*e/5

- Where AR is the average rating
- a is the number of 1 star ratings
- b is the number of 2 star ratings
- c is the number of 3 star ratings
- d is the number of 4 star ratings
- e is the number of 5 star ratings

This average formula is similar to how a weighted average is calculated. Each value is worth a different amount. For example, 4, 5-star ratings is worth 20 points and 3, 3 star ratings is worth 9 points. Take all of these values, add them up to a total, then divide by the number of possible ratings (5). This results in the average rating.
