The statistical features and general characteristics of an integrated statistical package, BC TRY, are reported. The BC TRY system of cluster and factor analysis includes many of the same descriptive and multivariate statistical analyses accomplished by the best of the packages reviewed by Berk (1977l, as well as some unique routines, and it provides the user with exceptional flexibility.Berk (l977) recently surveyed seven integrated packages of computer programs for statistical analyses. Selection was made on the basis of "frequency of use in descriptive and experimental research and compatibility with third-generation computers." The purpose of this paper is to document the statistical features and general characteristics of the BC TRY system of cluster and factor analysis (Tryon & Bailey, 1966 in a manner parallel to that employed by Berk. One of the first such packages to be developed, it continues to be widely used and much in demand. Originally written for the IBM 709 series, the programs are currently running on CDC 6400 (KRONOS operating system) and CYBER (NOS operating system) systems.The BC TRY system is an example of a higher order of "integration" than that offered by other statistical packages. The integration of most packages is very loose, with frequent points of incompatibility and inconsistency in data manipulation, data flow, and transmission of data to and from elements in the package. Functional aspects of the integrative elements of a package are important in its utility. Many packages, however, include components without the necessary focus on integration between components within the system. In this paper we describe some of the integrative features included in the BC TRY system.

“…Application of a cluster analysis technique developed by Tryon and Bailey (1966) provides a convenient way to examine changes in Ss' socially-induced views of the task. By treating distributions of cue values and S judgments as a set of variables which can be intercorrelated, factored, rotated, and plotted on a spheriod, this technique permits visual representation of Ss' cue dependencies.…”

Cognitive conflict as a function of socially-induced cognitive differences

The cognitive conflict model described by Hammond (1965) is based on the premise that cognitive differences may cause serious interpersonal conflicts, even in the extreme case of persons who are working together to attain a mutually desired goal. Empirical support for this premise has been obtained in several studies showing effects of cognitive differences upon subsequent conflict, learning, and compromise (e.g., Rappoport, 1965; Todd, Hammond, and Wilkins, 1965; Hammond, Todd, Wilkins, and Mitchell, 1967; Hammond, Bonaiuto, et al., 1967).However, these studies have all been experiments in which persons previously trained in the laboratory to think differently about an uncertain task disagree when they must make joint decisions concerning the task. If the cognitive conflict model is to serve as anything more than a laboratory analogue, it must be determined whether socially-induced ( i. e., &dquo;natural&dquo;) cognitive differences generate the same conflict phenomena as laboratory-induced (i.e., &dquo;artificial&dquo;) cognitive differences. This problem is investigated here by comparing the performances of S-pairs characterized by socially-induced cognitive differences and similarities with respect to a racial integration judgment task.The same problem was recently studied by Summers (1968). He also selected and compared S-pairs who thought differently and similarly about a racial issue. But, as we shall note in more detail later, his work primarily concerned the effects of rewards and instructions on conflict resolution. The present work is entirely concerned with appropriate methodology for studying conflict as a function of socially-induced cognitive differences. DesignThe study is based on selecting pairs of Ss whose thinking about racial integration is (a) different (negatively related), (b) similar (positively related), and (c) in-

“…Twenty-one elected and appointed student leaders in a large university were also surveyed. The supervisors' responses were dimension-analyzed by means of the BCTRY system for factor and cluster analysis (Tryon and Bailey, 1966).

EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT 1969, 29, 515-518. IN recent years, social scientists have become aware of the important role played by situational variables, both as an influence on group behavior and as a modifier of the relation between leader behavior and group performance. However, discussion of the importance of situational variables has not been accompanied by a concerted effort to develop comprehensive models and measures of situations.In an attempt to identify and measure situational variables other than the usual structural variables discussed in the management literature (e.g., Porter and Lawler, 1965), a leader situation description questionnaire was developed and validated. This 52 item questionnaire consisted of questions that appeared to be relevant to the behavior of formal leaders (e.g., task attributes, seriousness of performance errors for the organization, upward and downward influence of the leader, and formal role expectations for the leader). The selection of items was influenced by an earlier analysis of group dimensions by Hemphill (1956), a factor analysis of task dimensions by Shaw (1963), and leadership research carried out by Fiedler (1968).The new leader situation description questionnaire (LSDQ) was sent to a sample of 101 first-line supervisors (&dquo;foremen&dquo;) and second-line supervisors (&dquo;managers&dquo;) in two manufacturing companies and a public utility. Twenty-one elected and appointed student leaders in a large university were also surveyed. The supervisors' responses were dimension-analyzed by means of the BCTRY system for factor and cluster analysis (Tryon and Bailey, 1966). Scale scores were computed using the items with high factor loadings and reasonable &dquo;face validity&dquo;
