Kaiser and Michael reported a formula for factor scores giving an internal consistency reliability and its square root, the domain validity. Using this formula is inappropriate if variables are included which have trival weights rather than salient weights for the factor for which the score is being computed. (Author/RL)

Presents four tables for the statistical interpretation of factor scores on the Wechsler Intelligence Scale for Children-Revised. Provides the percentile equivalents of factor scores; the significance of differences between factor scores; the frequency with which specified discrepancies occur; the significance of differences between a factor score…

The Serlin-Kaiser procedure is used to complete a principal components solution for scoring weights for all options of a given item. Coefficient alpha is maximized for a given multiple choice test. (Author/GK)

This inventory measures sex guilt, hostility guilt, and morality-conscience guilt. Analyses indicate the appropriateness of a simple present-absent scoring system. Internal structure of each subscale is complex. Intercorrelations of scores are larger for males. (Author/BEF)

This study assessed the invariance in the factor structure of the "Test of English as a Foreign Language"™ Internet-based test (TOEFL® iBT) across subgroups of test takers who differed in native language and exposure to the English language. The subgroups were defined by (a) Indo-European and Non-Indo-European language family, (b)…

A mastery test is frequently described as follows: an examinee responds to n dichotomously scored test items. Depending upon the examinee's observed (number correct) score, a mastery decision is made and the examinee is advanced to the next level of instruction. Otherwise, a nonmastery decision is made and the examinee is given remedial work. This…

The purpose of this research was to further study the breadth and depth dimensions of the WAIS similarities and vocabulary subscales by factor analyzing several measures of intelligence: a comprehension index, SAT scores, and grade point average (GPA). (Author/SJL)

The concept of testing for partial knowledge is considered with the concept of tailored testing. Following the special usage of latent trait theory, the word valdity is used to mean the correlation of a test with the construct the test measures. The concept of a method factor in the test is also considered as a part of the validity. The possible…

A set of tests that might be reasonably used as provisional criterion measures in research on scientific thinking, particularly creative thinking, were developed and an assessment was made of the suitability of these tests as criterion variables from the standpoint of their psychometric properties. The Tests of Scientific Thinking are performance…

To assess the impact of various rating scale formats in rating student teachers, a Likert-type scale (Highly agree/slightly agree/neither/slightly disagree/highly disagree) was derived from the graphic scale currently used by the cooperating teachers and university supervisors. They rated the music student teachers on an eight-point scale from…
