If there are 20 good ratings, and 1 bad rating, out of 5 starts, what would the rating be?

Answer 1

To calculate the average rating given the distribution of good and bad ratings out of 5 stars, you need to follow these steps:

1. First, identify the value of each rating:
- Good ratings are 5 stars.
- Bad ratings' value will depend on what constitutes a "bad" rating. For this calculation, let's assume a bad rating is 1 star.

2. Calculate the total number of ratings:
- Number of good ratings: 20
- Number of bad ratings: 1
- Total ratings = 20 + 1 = 21

3. Calculate the total value of all ratings:
- Total value of good ratings = 20 ratings * 5 stars = 100
- Total value of bad ratings = 1 rating * 1 star = 1
- Total value of all ratings = 100 + 1 = 101

4. Calculate the average rating:
- Average rating = Total value of all ratings / Total number of ratings
- Average rating = 101 / 21

So, the average rating is approximately 4.81 stars.
