Say I have 10 features in my study and I would like to find out the WTP for say Printing speed with 5 levels in it (20, 24, 28, 35, 45, 70). I tried out the above way by giving 1 product the enhanced features and the other one the lowest features, but I am not able to get the result.
I am also doing the other way by dividing the $ range with the utility range and corresponding no. which i get, is being multiplied with the utility scores of each attribute. Say price range is 0 - 400 and utility range is -7 to 10. So diving 400-0/(10-(-7))=133. After which multiplying each utility score by 133. Please suggest if this is fine.
Kindly help as soon as possible.
