A novel use of periodic functions, called the periodic procedure, was recently introduced to make practical the use of certain physical measurement ideas in psychology. This paper reports a successful attempt to apply the periodic procedure to an important psychological measurement problem, the measurement of aptitude test item difficulties. The…

The problem of selecting the size of the tails from a sample drawn from a distribution of test scores for item analysis study is discussed. (Author)

This state-of-the-art review describes the genesis, structure, methods, applications, limitations and goals of the ordering analytic approach to hierarchical analysis, with specific reference to its relevance and use in educational, psychology and behavioral sciences. Hierarchy is defined as an "ordering" of objects such that the…

Conducts a comparative investigation of selected item analysis programs currently available which could serve as a base for judicious program selection and use. (RC)

The Q Sort method is a rank order procedure. A FORTRAN program is described which calculates a total value for any group of cases for the items in the Q Sort, and rank orders the items according to this composite value. (Author/JKS)

Some suggestions for computations are given for simultaneous determination of squared multiple correlations for all measures. (Authors)

The polyserial and point polyserial correlations are discussed as generalizations of the biserial and point biserial correlations. The relationship between the polyserial and point polyserial correlation is derived. Some practical applications of the polyserial correlation are described. (Author/JKS)

A new look at latent trait models is proposed. The event of an item being solved by a person is related to a person-specific random component and an item-specific random component. This allows for the interpretation of item discriminating power in terms of a product-moment correlation. (Author/JKS)

Since 1918, more than 280 measures of depressive severity have been developed and published. These measures differ in content, response format, and objectives. This article examines (a) the characteristics of scales developed in the past 80 years, and (b) the frequency with which different scales have actually been used in basic science and…

Research indicates the learning process among others things are influenced by have a diverse faculty. While the population of students in college across the United States is significantly more diverse than ever, diversity among faculty members did not concurrently occur (Smith & Moreno, 2006) and in order to maintain student diversity the…
