From a psychometric standpoint,________ questions are the weakest.

The scaling method that utilizes a rating from "Strongly Agree" to "Strongly Disagree" is called ________scaling.

The expression U - L)/N defines the

A ________scale presents the examinee with five responses ordered on an agree/disagree or approve/disapprove continuum.

_________________is a statistical index of how efficiently an item discriminates between persons who obtain high and low scores on the entire test.

A key step in using the Method of Equal-Appearing Intervals would be to:

A dichotomously scored test item with good item reliability must

____________has to do with accurate identification of patients with a syndrome.

Traditionally, the different ways of accumulating validity evidence have been grouped into three categories:
