Hello,

I have a site with a rating system to judge credibility of posted articles (sort of like Knol). The rating system is a scale from 1-5 stars, 5 being most credible. I need a way to "score" this information similar to what is done using the Binomial proportion confidence interval for "thumbs up thumbs down" binary rating systems. Unfortunately, I do not have a strong enough math background to understand the mathematics behind the confidence interval, so I'm wondering if anyone can point me in the right direction to try to accommodate that for my 5 star rating system. Thank you in advance!

The scoring supersedes "average rating" which is very unreliable because one five star rating would trump a thousand five stars and one two star.

With the way you are saying you are doing it, with the 5 stars, then if people don't see how many posts that person has done then they can't decide for themselves. You could always relate the number of posts into the rating, like have the actual rating of the number of posts, OR, just as a thought, if they have under a certain amount of posts, don't display the star rating and just say that they have not proven their rating yet. Simple.
