Aiken, Lewis R. – Educational and Psychological Measurement, 1983
A procedure and a computing diagram for assigning score boundaries to grading categories on classroom tests are described. The procedure takes both the median ability level of the class and the test performance of the class relative to that of other classes into account. (Author)

Aiken, Lewis R. – Educational and Psychological Measurement, 1985
Three numerical coefficients for analyzing the validity and reliability of ratings are described. Each coefficient is computed as the ratio of an obtained to a maximum sum of differences in ratings. The coefficients are also applicable to the item analysis, agreement analysis, and cluster or factor analysis of rating-scale data. (Author/BW)

Aiken, Lewis R.; Williams, Newsom – Educational and Psychological Measurement, 1978
Seven formulas for scoring test items with two options (true-false or multiple choice with only two choices) were investigated. Several conditions, such as varying directions for guessing and whether testees had prior knowledge of the proportions of false items on the test were also investigated. (Author/JKS)

Aiken, Lewis R. – Educational and Psychological Measurement, 1996
This article describes a set of 11 menu-driven procedures written in BASICA for MS-DOS based microcomputers for constructing several types of rating scales, attitude scales, and checklists, and for scoring responses to the constructed instruments. The uses of the program are described in detail. (SLD)

Aiken, Lewis R. – Educational and Psychological Measurement, 1994
Three dozen observations and recommendations concerning the activities of research consultants in the behavioral sciences are listed and discussed. These guidelines, some stated as aphorisms, are discussed in the categories of planning; implementation; analysis; interpretation; and reporting. (Author/SLD)

Aiken, Lewis R. – Educational and Psychological Measurement, 1987
Formulas for transforming scores and statistics on a rating scale having any number of categories to a scale having a different number of categories are described. To illustrate the use of one of the formulas, the means and variances of items on six forms of a course evaluation questionnaire were compared. (Author/LMO)

Aiken, Lewis R.; Aiken, Timothy A. – Educational and Psychological Measurement, 1986
Three exact probability tests, counterparts of t tests for single sample, independent samples, and dependent samples, are described for data obtained from ratings on "m" scales by a single rater or on a single scale by "n" raters. (LMO)

Aiken, Lewis R. – Educational and Psychological Measurement, 1983
Each of six forms of a 10-item teacher evaluation rating scale, having two to seven response categories per form, was administered to over 100 college students. Means of item responses and item variances increased with the number of response categories. Internal consistency of total scores did not change systematically. (Author/PN)

Aiken, Lewis R. – Educational and Psychological Measurement, 1992
The computation and determination of the statistical significance of three coefficients of interpersonal attractiveness or cohesiveness in task-oriented or social groups are described. The approach is based on ratings made by each member of a group of all other group members. Experience using the technique is reviewed. (SLD)

Aiken, Lewis R. – Educational and Psychological Measurement, 1989
Two alternatives to traditional item analysis and reliability estimation procedures are considered for determining the difficulty, discrimination, and reliability of optional items on essay and other tests. A computer program to compute these measures is described, and illustrations are given. (SLD)

Aiken, Lewis R. – Educational and Psychological Measurement, 1989
Two coefficients ("H" and "C") for evaluating the homogeneity or congruence of a set of ratings or scores are described. Statistical tests of the significance of these indexes are presented, along with a description of a computer program (CHOPRO) for determining values of "C" and "H" and associated…

Aiken, Lewis R. – Educational and Psychological Measurement, 1985
Procedures are described for determining the statistical significance of a set of ratings made on bidirectional (B) scales. B and its statistical significance can be determined on samples of items or raters. The statistical significance of a mean of B values can be assessed by applying a normal approximation test.

Aiken, Lewis R. – Educational and Psychological Measurement, 1982
Five types of multiple-choice items that can be used to assess higher-order educational objectives are examined. The item types do not exhaust the possibilities, but they are standard forms found helpful in writing items to measure more than recognitive memory. (Author/CM)

Aiken, Lewis R. – Educational and Psychological Measurement, 1980
Procedures for computing content validity and consistency reliability coefficients and determining the statistical significance of these coefficients are described. Procedures employing the multinomial probability distribution for small samples and normal curve probability estimates for large samples, can be used where judgments are made on…
