A Computer Program for Fisher's Exact Probability Test
Peer reviewed Peer reviewed
Tritchler, D. L.; Pedrini, D. T. – Educational and Psychological Measurement, 1975
Considered in this paper are a mathematical discussion and an algorithm, and a computer program for Fisher's test. (Author)

A General Multivariate Analysis of Variance Computer Program
Peer reviewed Peer reviewed
Woodward, J. Arthur; Overall, John E. – Educational and Psychological Measurement, 1974
Descriptors: Analysis of Variance, Computer Programs, Multiple Regression Analysis, Statistical Significance
A Computer Program to Test a Repeated Measures Hypothesis Using Hotelling's One-Sample T Squared Statistic
Peer reviewed Peer reviewed
Vitaliano, Peter P.; Halperin, Silas – Educational and Psychological Measurement, 1975

A Computer Program for Calculating Power of the F-test
Peer reviewed Peer reviewed
Woodward, J. Arthur; Overall, John E. – Educational and Psychological Measurement, 1976
Describes a computer program for calculating the power of the F-test. Approach is based upon two independent approximations-- a normalization of the non-central F distribution and an integration of the normal distribution. Comparison of the calculated values of power with exact values revealed a high degree of accuracy. (Author/RC)

An Alteration of Program UTEST to Determine the Direction of Group Differences for the Mann-Whitney U Test
Peer reviewed Peer reviewed
Jung, Steven M. – Educational and Psychological Measurement, 1971
Descriptors: Computer Programs, Hypothesis Testing, Nonparametric Statistics, Statistical Analysis
A Computer Program for the Johnson-Neyman Technique.
Peer reviewed Peer reviewed
Ceurvorst, Robert W. – Educational and Psychological Measurement, 1979
The Johnson-Neyman technique is briefly reviewed, and a program for carrying out an analysis using the procedure is described. The program accommodates one independent and one dependent variable, up to 20 groups of observations, and an unlimited number of cases. (Author)

Mixed Effects MANOVA Using BMD12V.
Peer reviewed Peer reviewed
James, Michael – Educational and Psychological Measurement, 1979
Details are given for the use of the mixed effects multivariate analysis of variance table provided by the BMD12V computer program to compute raw generalized variances and hence the U and F statistics for the mixed effects model. (Author/JKS)
Descriptors: Analysis of Variance, Computer Programs, Hypothesis Testing, Program Descriptions
An Avoidable Error in a Posteriori Testing.
Peer reviewed Peer reviewed
VanBerschot, S. N. – Educational and Psychological Measurement, 1979
An error is described that may occur in a posteriori testing, particularly when the original analysis of variance produces an F ratio that is just barely significant and the computer printout of the analysis does not provide the means that were used in the program. (Author/JKS)
Descriptors: Analysis of Variance, Comparative Analysis, Computer Programs, Statistical Significance
Computer Programs for Robust Analyses in Multifactor Analysis of Variance Designs
Peer reviewed Peer reviewed
Games, Paul A. – Educational and Psychological Measurement, 1975
Describes a set of five programs providing robust techniques that work well when the assumption of conventional analysis of variance have been violated. (Author/RC)
Descriptors: Analysis of Variance, Computer Programs, Matrices, Research Design
A Computer Program for Nonparametric Post Hoc Multiple Comparisons
Peer reviewed Peer reviewed
Roberge, James J. – Educational and Psychological Measurement, 1971
Descriptors: Analysis of Variance, Computer Programs, Hypothesis Testing, Mathematics
The Analysis of Multivariate Group Differences
Peer reviewed Peer reviewed
Gross, Alan L. – Educational and Psychological Measurement, 1975
Describes the MANOVA (multivariate analysis of variance) Computer Program for ascertaining whether k groups differ significantly from one another on p dependent variables. (Author/RC)
Descriptors: Analysis of Variance, Computer Programs, Groups, Hypothesis Testing
A Study of the Effect of the Violation of the Assumption of Independent Sampling upon the Type I Error Rate of the Two-Group t-Test
Peer reviewed Peer reviewed
Lissitz, Robert W.; Chardos, Steve – Educational and Psychological Measurement, 1975
Describes some of the situations in which a psychologist is likely to violate the assumption of independent errors. A Monte-Carlo study of the effects of this violation is then described. (Author/RC)
Descriptors: Analysis of Variance, Computer Programs, Hypothesis Testing, Matrices
An Algorithm for a Randomization Test
Peer reviewed Peer reviewed
Ray, William S.; Schabert, Stanley A. – Educational and Psychological Measurement, 1972
The program with extensive annotation is available in an unpublished dissertation (Schabert, 1970). (Authors)
