  • Validity of the Standard Progressive Matrices as a Predictor of Achievement of Sixth and Seventh Grade Students

    Open AccessStephen Powers, P Berthon Jones et al.ARTICLEEducational and Psychological…1986

    The predictive validity of the Standard Progressive Matrices(SPM) was examined with a sample of 212 sixth grade students and 214 seventh grade students. Correlation coefficients between the SPM and the California Achievement Tests of Reading, Language, and Mathematics ranged from .34 to .60. Those coefficients were similar in range and magnitude to those coefficients reported by the SPM Manual

  • A Basic Computer Program for Calculating Simultaneous Pairwise Comparisons in Analysis of Covariance

    Open AccessStephen Powers, P Berthon Jones et al.ARTICLEEducational and Psychological…1986

    This paper describes a BASIC microcomputer program that computes all pairwise comparisons of means after analysis of covariance using the Tukey-Kramer test. Input to the program consist of the means of the covariate, the adjusted criterion means, the sample size, mean square error from a one-way analysis of covariance, and the 95th percentile point on the Studentized range distribution

  • Two Basic Programs to Compute Hotelling's T2 Statistic

    Open AccessStephen Powers, P Berthon Jones et al.ARTICLEEducational and Psychological…1986

    This paper describes two BASIC computer programs that calculate Hotelling's T 2 statistic either for one sample or for two samples. Output of the program includes the Mahalanobis distance D 2 , the F ratio associated with T 2 , and its probability level

  • Comparison of Item Responses of English- and Spanish-Speaking Children Using Minimum Logit Chi-Squared Regression

    Open AccessStephen Powers, Michael J Wagner et al.ARTICLEPsychological Reports1986

    A total of 102 Spanish-speaking preschool pupils and 104 English-speaking pupils were individually administered the Spanish and English versions of the Cooperative Preschool Inventory. Minimum logit chi-squared regression was applied to each of the 33 items of the verbal scale of the inventory. Several differences in the response patterns of the two groups were noted, although the number of potentially biased items was small (12%)

  • Reliability and Validity of the Language Proficiency Measure

    Open AccessStephen Powers, Donna M Johnson et al.ARTICLEEducational and Psychological…1985

    A total of 101 English-speaking Hispanic and 97 Spanish-speaking Hispanic pupils in Grade K-3 were administered the Language Proficiency Measure (LPM). Results indicated that the interrater reliability was adequate, internal-consistency reliability estimates were high, concurrent validity coefficients were adequate, and the classification validity was acceptable. These findings provided substantial evidence supporting the reliability and validity…

  • Factorial Invariance of the California Achievement Tests Across Race and Sex

    Open AccessStephen Powers, P Berthon Jones et al.ARTICLEEducational and Psychological…1984

    The six subtests of the California Achievement Tests were factor analyzed separately for black males, black females, Hispanic males, Hispanic females, white males, and white females in the fifth- and seventh-grades. One factor best described the factor structure of the test of each group. The structures of each group were compared by using coefficients of congruence. The California Achievement Test was found to be essentially invariant with regar…
