Converting MaxDiff Scores to 1 to 10 rating


Can we somehow convert the MaxDiff scores in 1 to 10 ratings.

You can rescale MaxDiff utilities easily enough if you want to, but that doesn't  make them ratings.  

For example, you might take the lowest MaxDiff score for a respondent (say it's a -4) and the highest (say it's a +5.3).  Now, just divide that range into tenths, so that you have the range -4 to -3.07, -3.071 to -2.14 and so on to 4.37 to 5.3.  Now just put the respondent's MaxDiff scores into those range-buckets and you have a 1-10 rescaling of the items' utilities.  

No doubt there are other ways to do a 1-10 rescaling, but again, I'd be hesitant to call any of them "ratings."
