Rating the Raters A new statistical method for evaluating

In this paper, with the actual data of a lecture contest,prevailing method’s defects to remove a maximum score and a minimum score, average of the rest to determine the ranking of the contestants are found. Comparison of three methods of evaluation that prevailing method, calculating raters’ weight once and Iterative calculation their weight, we design a quantitative method to reduce the judges’ weight who have larger deviation, increase their weights who have smaller one, so that the final result is more accurate. In addition, the computer programs of the three evaluation methods are also developed to facilitate the practical application. Keywordsrater; weight; iterative algorithm; computer program
