Sometimes I see posts about ratings so I just wanted to make this brief post to allay any confusion.
1. When you see the stars next to a course that is NOT the average
2. Ratings: The rating of your course is the star rating that appears with your course wherever it is advertised. Udemy utilizes weighting ratings based on the level of usefulness and relevance of the rating. There are a number of factors we’re using to help weight ratings; however, three of the most significant are:
-Amount of the course the student consumed before leaving the rating
-How recently the rating was left
-How valuable the student’s feedback was to instructors and students
With this in mind, your course rating is not a pure average of all reviews, but each individual review may be weighted differently based on all the factors Udemy considers.
3. You could receive two 5 star ratings and one 5 star review and no other ratings/reviews but the stars next to your course could be (for example) 4.5
No I don't see how it does.
Then I could see how it could (for example) be 4 star, yes.
But if no-one ever gave less than 5 star and if one of those 5 star was a review then I don't see how it can possibly be less than a 5 star.
If only ONE person gave a rating and that was 5 star then, using the logic, the average could be 4.5 (for example if the 5 star was after 1%) but even that seems strange because if everyone gives 5 star then no-one at all thinks it is less than...5 star.
Spot on. weighted average should come into picture only when at least 2 or more different numbers are given in rating. For example if one 5, one 3.. Your rating should vary from 3 to 5 based on the above logic. If only one rating. The display rating has to be same
