I am trying to device a algo for product score. Here are the inputs
- User rates a product on 5 different criteria out of 10
- Each criteria has a different weightage with all adding up to 100%
- There are 3 types of user expert, inter, beginner
- Again weightage of users is different
Here is what i have thought
We get the final score for each user out of 10 by
User score = CriteriaScore 1 * Weight 1 + CriteriaScore 2 * Weight 2 + ... + CriteriaScore 5 * Weight 5
Expert gets a weight of 3, inter get a weight of 2 and beginner gets a weight of 1
Final score = Avg Final score of expert * WeightExpert + Avg Final score of inter * WeightInter + Avg Final score of beginner * WeightBeginner
But my formula doesn't take into account How many people rated the product. How do i get this data into the picure.
Any other suggestion is also welcome
