In the paper the issues of reducing the uncertainty of expert assessment weight coefficients are considered. To achieve this task the median Walsh was used. A sequence of calculating the weighting coefficients and their expanded uncertainty using a median average and median Walsh is given. Using ordinal statistics, the comparison of the results of calculating the probability of finding the median and median Walsh at a specified interval was performed and it demonstraits greater effectiveness of median Walsh.
