Lord’s approximation to the standard error of
measurement of a test uses only n, the number of
items. Millman’s is based on n and p̄, the mean
difficulty. Saupe has used Lord’s approximation to
derive an approximation ...
A class of naive estimators of correlation was
tested for robustness, accuracy, and efficiency
against Pearson’s r. Tukey’s r., and Spearman’s ro.
It was found that this class of estimators seems in
some respects to ...
Consider a reliability study in which different
subjects are judged on a dichotomous trait by different
sets of judges, possibly unequal in number.
A kappa-like measure of reliability is proposed, its
The ordering power of an objective test was defined
in terms of the probability that this test led to
the correct ranking of examinees. A comparison of
the relative ordering power of separate and
grouped-items true-false ...
A method for computation of dominance relations
and for construction of their corresponding
hierarchical structures is presented. It is shown that
variance can be computed from the squared pairwise
differences between ...
