Rating system for site materials

Question

Algorithms

Tell me what rating system to choose for evaluating materials? There are two types of materials, the first one is rated from 1 to 5, the second one is rated from 1 to 10. The biggest problem is how to evaluate a material in which there are many ratings, for example, out of 1000 ratings, let's say that most of the ratings are 4 and there are several ratings of 3. There is a second material in it in total 10 ratings and all 4, but this does not mean that the second material is better than the first. How to be?

Answer 1

All such methods are initially very approximate and subjective assessment, so it is strange to try to do it “right” and fairly estimate the best material. In a good way, among these people there are probably people who are competent in these materials, whose assessments are much more important than the rest, and there is the bulk of amateurs, whose assessments do not affect at all and even harm in your case. You can’t even distinguish them, well, now what can you do. Look even at grades, ratings, karma on Habré. How much do they show? Especially the best materials. Calculate the average and write in brackets (1000 ratings) how everyone is doing and do not invent)

Answer 2

alternatively, you can replace the ratings as such with the “level of activity” on the site. Thus, we will not find fault with an amateur user or a specialist in the matter.
