- Summary:
-
Written as a technical report for the leadership course of the United States Naval Academy (see the final reports which summarize the course development project, EM 010 418, EM 010 419, and EM 010 484), this paper examines the use and interpretation of the rank-biserial correlation as an index of item discrimination. The advantages and disadvantages of this index are compared with those of alternative indices derived from the response of upper and lower groups divided on the basis of total test scores. Computational procedures and tests of statistical significance for the rank-biserial correlation are presented. Appropriate correction for the spurious correlation arising from the contribution of the item to total scores is also provided. (Author/SH)
