The power of statistical tests based on four popular
product-moment correlation coefficients was examined
when relatively small samples (10 ≤ N ≤ 100) are
drawn from bivariate populations of several different

This paper presents a new stochastic three-way unfolding
method designed to analyze asymmetric three-way,
two-mode binary data. As in the metric three-way
unfolding models presented by DeSarbo (1978)
and by DeSarbo and ...
The purpose of the present study was to examine
the effect of response format—open-ended (OE) versus
multiple-choice (MC)—on the diagnosis of examinee
misconceptions in a procedural task. A test in fraction
Simulated data were used to investigate systematically
the impact of various orderings of step difficulties
on the distribution of item information for the partial
credit model. It was found that the distribution ...
The person response curve has been suggested as a
possible model for test score inappropriateness (Lumsden,
1977, 1978; Weiss, 1973). The two-parameter
person response curve proposed by Lumsden includes
a person slope ...
