Different users of the site are giving rating of the seller. I want to calculate the positive feedback in percentage of seller. I am showing the database of the single seller In My Feedback table data is storing as follow :
Note : reliable max : 5, communication max : 5, experience max : 3 (1=poor, 2= average, 3 = good)
User one rating to Seller reliable : 4 communication : 5 experience : 3
User two rating to Seller reliable : 5 communication : 1 experience : 2
User three rating to Seller reliable : 5 communication : 5 experience : 3
and other users rating will go in this fashion
how do i calculate the Positive feedback of the Seller?
