This site has pretty complicated weighted rating calculation method, which you can find in documentation. Not clear what is your problem.

Solution 1

It is up to you to decide based on your own rules. For example you could allocate a basic number of points for each star that a poster gives to an entry, such as:

1 star = -2 point
2 stars = -1 point
3 stars = 2 points
4 stars = 4 points
5 stars = 6 points

You can then add weights to those values based on the user's reputation; so multiply the base points by the weighting value to give the final points allocated. Then decide how many points per star and that is your final value.

Thanks for Reply..Plz Can you give some more detail.

Flex_Query 2-Jul-12 6:02am

If I allocated basic number of points for each star, such as
1 star = 1 point
2 stars = 2 point
3 stars = 3 points
4 stars = 4 points
5 stars = 5 points

For Example:
Users gave some star value to particular Reply Mean.
3 Person gave 5 Stars, So = 3* 5 = 15
2 Person gave 2 Stars, So = 2 *2 = 4
Calculation = 15 + 4 = 19
Finally, Rating for that Answer is = 19/5 = 3.8
Is This Correct or Not, Please Reply.

Is this correct? If that is the way you wish to do your calculations, then yes. As I said before it is up to you to decide what you want and then figure out the algorithm you need to achieve that result.

Thanks Richard.Can u give some idea about algorithm usage for my calculation.

Richard MacCutchan 2-Jul-12 6:44am

I already said that you need to work it out for yourself. I have no idea what your rules are going to be so I cannot write the algorithm.
