A flexible Fortran program for computing a complete analysis of covariance is described. Requiring minimal core space, the program provides all group and overall summary statistics for the analysis, a test of homogeneity of regression, and all posttest mean comparisons for a priori or a posteriori testing. (Author/JKS)

Programs are described for the construction and analysis of student evaluation questionnaires and rating scales that are custom-designed for individual course instructors. Minor modifications would permit the use of these programs for other kinds of questionnaires and rating scales as well as for achievement tests. (Author)

This article presents a computer program designed to produce questionnaires based upon the multiple rank orders method. These questionnaires may be used as attitude measurement instruments. (Author)

A Fortran program is presented that administers, scores, and interprets the Interpersonal Check List. Included in the program are test items, protocols for administration and scoring, printing of individually-tailored interpretation of results, and a pictorial plot describing the characteristic interpersonal behavior in terms of two orthogonal…

The autoregressive integrated moving averages model (ARIMA) has been applied to time series data in psychological and educational research. A program is described that generates ARIMA data of a known order. The program enables researchers to explore statistical properties of ARIMA data and simulate systems producing time dependent observations.…

This paper provides a mathematical algorithm for Fisher's exact probability test which is adaptable to contingency tables greater than two by two, and which provides the user with an index of predictive association designed for crosstabulations of nominal level variables. (Author/JKS)

A description of a Fortran program for linear and area transformations of test scores with optional generation of symmetric tables of areas under the standard normal curve is presented. Also included is a historic note on the origin of McCall's T Scale. (Author/JKS)

A computer program is described which provides point-biserial coefficients of correlation and comprehensive response analyses for tests, questionnaires, and rating scales. The program can be executed with as few as three control cards. Data with missing observations, and more than one data deck can be analyzed at one time. (Author/JKS)

A computer program providing comprehensive test and item analysis is presented. Completing its performance on one run, the program, written in Fortran and emphasizing ease of use, integrates various statistical techniques for analyzing individual items and the overall test, in addition to generating a variety of standard scores. (Author/JKS)

This program generates maximum likelihood estimates of the parameters of a mixture of two normal distributions and tests the significance of the mixture hypothesis against that of a single normal distribution. (Author)
