How to correctly get the rating percentage based on negative and positive ratings?

Question

Ratings

Good evening.
I need to get a percentage of the rating to form 1-5 stars, as is usually done in online stores. What is the best formula to use? The rating is formed on the basis of positive and negative user ratings + optional quality control rating.

Answer 1

the task is wider than it seems and does not have a single answer,
so you can think of it as you like - skin factor, etc.
