The weighting method used was based on that proposed by Davis, which involves taking the upper and lower 27% of a sample, according to some criterion measure, and using the percentages of these groups marking an item option…

It was concluded that option weighting offered limited, if any, improvement over unit weighting. (Author/CTM)
