The statistics and measurement items were administered in classes where graduate students taking the test were studying the content. Vocabulary items represented…

This study compared the item difficulty and item discrimination of three multiple choice item formats. The multiple choice formats studied were: a complex alternative (none of the above) as the correct answer; a complex alternative as a foil, and the one-correct answer format.

The comparative effects of various sequences of test items were examined for over 900 graduate students enrolled in an educational research course at The University of Alabama, Tuscaloosa. experiment, which was conducted a total of four times using four separate tests, presented three different arrangements of 50 multiple-choice items: (1)…

Equivalence in reliability and validity across 4-point and 6-point scales was assessed by fitting different measurement models through confirmatory factor analysis of a multitrait-multimethod covariance matrix. Responses to nine Likert-type items designed to measure perceived quantitative ability, self-perceived usefulness of quantitative…
