Approval Ratings or customer reviews are just weighted/simple mean of all feedback scores given by a set of customers. These scores are dynamic and change as and when new feedback data is fed in. There is no way to predict the final score after a particular number of feedbacks would be achieved. Also there is no way to know the instantaneous variablitity in the score. Comparing and ranking products as per customer reviews is absurd since the number of feedbacks may not be same for these products. The below article is a mathematical way to sort out all these issues. It helps us predict the final score and also gives us instantaneous variability at any point.
