Counterplans have become commonplace in intercollegiate debate, yet misconceptions abound. This article attempts to integrate thinking about counterplans with general debate theory. It reexamines the issue of topicality and sketches the basis for comparison of affirmative proposals with negative counterplans in the areas of presumption, inherency,…

Monte Carlo techniques were employed to compare the familiar F-test with Welch's V-test procedure for testing hypotheses concerning a priori contrasts among K treatments. The two procedures were compared under homogeneous and heterogeneous variance conditions. (Author)

This experiment is concerned with delineating various aspects of pretraining that contributed to the improved hypothesis-testing strategies of 150 kindergarten children. (MP)

This study tested three versions of the "abuse-to-abuser" hypothesis by comparing men with personal histories of sexual abuse and men without sexual abuse histories. There was a statistically non-significant trend for assaulted offenders to be more likely as adults to commit genital assaults on children. Implications for the abuse-to-abuser…

Five methods for testing the hypothesis of independence between two sets of variates were compared through simulation. Results indicate that two new methods, based on robust measures reflecting the linear association between two random variables, provide reasonably accurate control over Type I errors. Drawbacks to rank-based methods are discussed.…

The efficacy of two types of therapy conducted exclusively over the telephone was studied. Clients (N = 55) were recruited from a pool of callers to a suicide hotline and were randomly assigned to a waiting list control (WC) or Solution Focused Brief Therapy (SFBT) or Common Factors Therapy (CFT). It was hypothesized that improvements would be…

Contingency tables, and their associated statistical tests, are frequently used in educational and social research. Popular statistical tests used in contingency table analyses include the Pearson chi-square test and the likelihood ratio chi-square test. These two tests are chi-square distributed under large sample conditions. However, when a…

The hypothesis that the normal effects of recreationally used drugs vary across substances, users, and situations as a function of normative content, normative clarity, and situational context was tested. (Author/JC)

Some aspects of simultaneous tests for means are reviewed. Specifically, the comparison of univariate or multivariate normal populations based on the values of the means or mean vectors when the variances or covariance matrices are equal is discussed. Tukey's and Dunnett's tests for multiple comparisons of means, Scheffe's method of examining…

This study explores the speculation that unidentified factors such as organizational complexity might account for disparate research findings regarding the relationship between the administrative component and organization size. Complexity and size of organization were found to be significantly related variables, although there is no evidence to…

Thirty subjects were presented with a visual form discrimination task requiring them to match Roman letters when a variety of transformations were held constant. They were given massed practice across four blocks of eight stimuli. Results of a repeated measures analysis of variance showed support for the distinctive features hypothesis. (JC)

This paper develops a general method for comparing treatment magnitudes for research employing multiple treatment fixed effects analysis of variance designs, which may be used for main effects with any number of levels without regard to directionality. (Author/BS)

Details of a reasonably precise normalization technique for coefficient alpha are outlined, along with methods for estimating the variance of the normalized statistic. These procedures lead to the K-sample significance test. (RC)

This paper describes two statistics (chi square and Kendall's S) which may be used to test hypotheses about the association between two variables when observations are cross-classified in a contingency table. (CK)
