The present study was designed to examine the construct validity, reliability, item difficulties, discrimination indices, effectiveness and efficiency of the CCAT test. (Author)

Two indices of profile reliability are shown to be equivalent in terms of the individual independent canonical composites; however, because of different weighting procedures, they yield different overall indices of profile reliability. A common formula is provided from which both indices can be derived. (Author)

The purpose of this empirical study was to establish initial reliability and validity data for a new Television Test of Science Processes (TTSP) which was developed in conjunction with the Science for the Seventies project of televised science instruction modules. Reliability was determined through internal consistency analysis using the…

Three techniques for estimating Kuder Richardson reliability (KR20) coefficients for incomplete data are contrasted. The methods are: (1) Henderson's Method 1 (analysis of variance, or ANOVA); (2) Henderson's Method 3 (FITCO); and (3) Koch's method of symmetric sums (SYSUM). A Monte Carlo simulation was used to assess the precision of the three…

The basic qualities which questionnaires must have in order to serve best the purpose for which they are designed are emphasized. A description of the preliminary planning necessary to questionnaire construction, as well as the construction of the form itself, is provided. Various types of questionaire items and the advantages and disadvantages of…

The S.I.T. is an age scale of intelligence with demonstrated reliability and high validity coefficients correlated to the Stanford-Binet. The items of the SIT were classified according to a scheme resembling Valett's classification of Stanford-Binet test items. A comparison of the classifications is made. (Author)

Interrater differences in scoring actual WISC protocols were determined for three different IQ levels. In general, differences among the 94 examiners tended to be within an acceptable range as established by the standard error of measurement; variance on two Verbal subtests occasionally exceeded their corresponding standard error of measurement.…

In the face of the deliberations that have been taking place in England for several years now about the merging of two '16+' examinations, the CSE and GCE Ordinary level, author investigated the French system and the examination, the BEPC, taken at 'intermediate' level by 'average' and 'above average' students.

Examines the content and construct validity of the Barth Scale. Latent partition analysis generated item content categories for judgmental data gathered from open education experts; factor analysis described constructs generated from response data gathered from open and traditional elementary school teachers.

Assessed the validity of reports on family social status by comparing responses of co-twins. Co-twin agreement on factual items about their family is a particularly good criterion for evaluating the validity of a socioeconomic status measure. (RC)

Explores the usefulness of a short version of the Minnesota Multiphasic Personality Inventory (Mini-Mult) in a university counseling center as well as determines whether earlier results of investigations of the Mini-Mult could be replicated with a sample of college males and females demonstrating no gross abnormalities.
