A debate about qualitative versus quantitative analysis has been waged in the scientific community for several years. A different set of parameters is suggested for this debate, and a logical transformation is outlined that makes the qualitative/quantitative distinction at the epistemological level a non-problem. While the strategy of induction…

Studies of human problem solving have traditionally used deterministic tasks that require the execution of a systematic series of steps to reach a rational and optimal solution. Most real-world problems, however, are characterized by uncertainty, the need to consider an enormous number of variables and possible courses of action at each stage in…

Few phenomena in psychology have been studied more than reaction time. However, while response latency now provides the basic data for research in many areas of cognitive psychology, little work has been done on the problem of incorporating response latency in the measurement of individual differences. A solution to this problem requires the…

With the implementation of the all volunteer force concept, the Air Force must ensure that the objectively measurable range of ability in its manpower pool is being utilized. This is especially true for minority groups who have been categorized and channeled into military career areas based on their performance on two selection tests: the Armed…

In a previous study, (ED 038 175) Mississippi children, who were a year younger (3 1/2 to 4 1/2) than Alabama children, had scored higher than the Alabama children on posttesting. This supplementary report gives the results of further investigation of this finding. Explanations may be: (1) the younger children began with higher IQ scores; (2) more…

The Bureau of Indian Affairs' (BIA) Higher Education Program was evaluated in order to provide valid information for decision making. Data gathered by a questionnaire administered to 2,736 students in a previous study was refined by applying the chi-square test of significant differences to certain student characteristics and variables. Each area…

Three topics in factor analysis are covered: a) a reliability coefficient for assessing the quality of a maximum likelihood factor analysis, b) an application of three-mode factor analysis to serial learning data, showing variations in learning curves over stages of learning and individuals, and c) the use of personal probability functions to…

The study tests hypotheses derived from the proposition that open education promotes self-concept. The Sear's Self-Concept Inventory, yielding scores in six self-concept "areas," was administered to 316 students, ages 9 to 12, from six suburban schools. The Walberg-Thomas Scales rated each school as to degree of openness. No significant…
