Too many simple clerical scoring errors: the Rey Figure as an example.
The clerical errors from 325 scored Rey Figure drawings were tabulated using the procedures outlined in the Boston Qualitative Scoring System manual. The error types investigated were avoidable quantitative scoring errors (e.g., addition, using conversion tables, and plotting scores). The three scorers made errors on 18.3%, 22.4%, and 24.7% of the Rey Figures they scored.
