A Subroutine for Computing Item Efficiency and Associated Probabilities
Peer reviewed Peer reviewed
Hofmann, Richard J. – Educational and Psychological Measurement, 1975
Descriptors: Computer Programs, Item Analysis, Probability
Computer Procedure to Compute Unweighted Means Analysis for Two-Factor Fixed Effects Analysis of Variance
Peer reviewed Peer reviewed
Smith, Robert A.; And Others – Educational and Psychological Measurement, 1977
A FORTRAN computer program is described which computes F ratios and attendant probabilities for two-factor fixed effects analysis of variance designs with disproportional cell frequencies. The number of levels for each factor is limited to five and all zero values are considered to be equivalent to missing values. (Author/JKS)

A Program for Calculating the Exact Probability Along with Explorations of M by N Contingency Tables
Peer reviewed Peer reviewed
Fleishman, Allen I. – Educational and Psychological Measurement, 1977
A computer program for testing the association of two nominal variables using Fisher's exact probability test is described. Theoretical corrections according to recent literature are made. Various methods of discovering the source of association at the cellwise level are given. (Author/JKS)

A Program for Computing Fisher's Exact Probability Test and the Coefficient of Association LAMBDA for n x m Contingency Tables
Peer reviewed Peer reviewed
Bedeian, Arthur G.; Armenakis, Achilles A. – Educational and Psychological Measurement, 1977
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 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)

Manipulations with Multiple Choice Tests: A Probability Function of a Total Testscore
Peer reviewed Peer reviewed
Dyck, Walter; Plancke-Schuyten, Gilberte – Educational and Psychological Measurement, 1976
Previous knowledge of the difficulty index and the intercorrelations of the items will allow group results to be predicted and manipulated. A compound bionomial probability function of a testscore is established for which a computer program has been written. Three item selections and the appropriate probability distributions are given which give…

A Computer Program for Estimating the Power of Tests of Assumptions of Markov Chains
Peer reviewed Peer reviewed
Lissitz, Robert W.; Halperin, Silas – Educational and Psychological Measurement, 1971
Descriptors: Behavioral Science Research, Computer Programs, Hypothesis Testing, Mathematical Models
Content Validity and Reliability of Single Items or Questionnaires.
Peer reviewed Peer reviewed
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…
