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

Comparison of three microcomputer statistical packages, SPSS, SAS, and BMDP, focuses on ease of use, ease of learning, documentation, accuracy, similarity to the mainframe version, and speed. The results of eight statistical multivariate analyses used to evaluate their performance are given. (LRW)

Describes the use of a simulated learning environment (SLE) as an instructional aid in teaching multivariate statistics, particularly inferential statistics. A prototype microcomputer-based SLE called MVWORLD developed at Drexel University for upper level statistics courses is explained, and implementing a statistics laboratory for multivariate…

Describes a study that was designed to examine whether the computer attitudes of graduate students in a beginning statistics course differed based on their prior computer experience and the type of statistical analysis package used. Versions of statistical analysis packages using a mainframe and a microcomputer are compared. (14 references) (LRW)

Examines the relationship between computer anxiety and computer experience for older (over 55) and younger (under 30) adults. Data were collected from 422 subjects using attitude and anxiety scales. Results indicated that older adults were less computer anxious than younger adults but had less computer confidence. No gender differences were found…

Examines factors involved in decisions regarding adoption of microcomputers for administrative and instructional use in early childhood education. A study of 80 administrators in Illinois is described and analyzed that considered relevant past experiences, future expectancies, openness to change, and social support as decision-making influences.…

The effects of microcomputer use on preschoolers' knowledge of pre-reading concepts and attitudes toward microcomputers were investigated. Seventy-seven preschoolers were randomly assigned to three treatment conditions: (1) adult-assisted microcomputer instruction; (2) unassisted microcomputer use; and (3) no computer use. Analysis of pretest…

STATGRAPHICS, a statistical package written for the IBM PC/XT/AT, is reviewed. In addition to superb graphics, STATGRAPHICS is unequalled in time series procedures, quality control, linear programming, and other mathematical procedures. The modules for regression analysis, categorical data analysis, and nonparametric analysis are good, but contain…

Reports the development of a classification system for microcomputer-based software according to the depth and type of involvement of the user with the software. Three studies are discussed that used the facet approach, multivariate statistical procedures, and questionnaires to investigate types of involvement produced by computer programs. (18…

Discussion of computer-based instruction and animation focuses on a study of undergraduates that investigated the effects of two computer-based instructional strategies, visual display and feedback type, on teaching how to troubleshoot electronic circuits. Time spent on various components of the program is also examined. (35 references) (LRW)

Describes a study that investigated how to teach computer skills to undergraduate female novice users through the design of an instructional manual that facilitated learning computer skills and increased computer self-efficacy by using familiar analogies. Treatment of the experimental and control groups is explained, and measurement techniques are…

Describes study that investigated the effects of learner control and program control on the achievement and continuing motivation of high school students. The influence of the availability of computer-delivered instruction on student motivation was also examined, results are analyzed, and further research needs are suggested. (37 references)…

Describes a study that examined the evolution of students' perceptions in grades 4 through 10 concerning computers over the course of 3 years. The use of Clark's concept of media attributions is explained; and results related to the three dependent variables of preference, perceived learning, and perceived difficulty are reported. (32 references)…

Describes research that investigated the study strategies of preservice teachers through the use of a hypertext program that monitored lecture note review strategies of individuals and dyads. Highlights include learning from lectures; the use of pretest information; and differences in dyad and individual review strategies. (Contains 28…

Discussion of short-term and long-term memory in learning paired associates focuses on two microcomputer-based instructional design experiments with eleventh and twelfth graders that were modeled after traditional drill and practice routines. Research questions are presented, treatment conditions are explained, and additional research is…
