Consider the scenario where M performances (eg. singing contest) are being judged by N judges. Each judge awards a score S(m,n) to each performance on a scale of one to one-hundred.
The problem occurs when each judge has an individual style of using the scale. For example Judge A might give the worst performances a minimum of 30 and the best a maximum of 90, while Judge B may handout the minimum as 10 and the maximum as 80.
How do we regularize the scores so as the get the overall correct score? Some justification (link to an article or paper) for the answer would be appreciated.
This is similar to https://stats.stackexchange.com/questions/138973/normalizing-interview-scores, but that question has received no responses.
