We are starting an price comparison website of online products which compares the prices of various products in online stores.We need help in comparing ratings of a product.Please go through below scenario
This product having 100 reviews from the customers and rating is 4.0.
This product having only 5 reviews from the customers and rating is 5.0.
In the above case how can I decide which product is good or quality one.Based upon the ratings(4.0 and 5.0),we cant judge product B is good.On what parameter I should evaluate the product quality.Please help me friends,I need a formula to calculate the accurate rating for the products.Its will be a big help to us.
