Alternative methods to correct for rater
leniency/stringency effects (i.e., rater bias) in performance
ratings were investigated. Rater bias
effects are of concern when candidates are
evaluated by different raters. The ...
The effectiveness of smoothing the bivariate
distributions of common and noncommon item
scores in the frequency estimation method of
common-item equipercentile equating was examined.
The mean squared error of equating ...
The marginal maximum likelihood estimation
(MMLE) procedure (Bock & Lieberman, 1970; Bock
& Aitkin, 1981) has led to advances in the estimation
of item parameters in item response theory.
Mislevy (1986) extended this ...
Determining a correct response to many test
items frequently requires more than one ability.
This paper describes the characteristics of items of
this type by proposing generalizations of the item
response theory ...
This study investigated the effectiveness of the
Mantel-Haenszel (MH) statistic in detecting differentially
functioning (DIF) test items when the
internal criterion was varied. Using a dataset from
a statewide ...
