This report provides the statistical tools necessary to measure the extent of error that exists in organizational record data and group survey data. It is felt that traditional methods of measuring error are inappropriate or incomplete when applied to organizational groups, especially in studies of organizational change when the same variables are…

The four main approaches to measuring treatment effects in schools; raw gain, residual gain, covariance, and true scores; were compared. A simulation study showed true score analysis produced a large number of Type-I errors. When corrected for this error, this method showed the least power of the four. This outcome was clearly the result of the…

Regression formulations and related concerns involved in dealing with wage discrimination suits involving college faculty are considered. Several models based in hypothesis testing "policy capturing" uses of multiple linear regression are presented, and problems related to the court's view of statistical significance are examined.…

Action research often necessitates the use of intact groups for the comparison of educational treatments or programs. This paper considers several analytical methods that might be used for such situations when pretest scores indicate that these intact groups differ significantly initially. The methods considered include gain score analysis of…

The major purpose of this study was 1) to investigate the development of the concept of a unit of measure and the coordination of unit size and the number of units 2) to relate this development to the development of conservation and 3) to determine the role of equivalence and nonequivalence relations in certain conservation and measurement…

The mission statements of 34 four-year and of 68 two-year colleges in the State of Texas were examined for themes to determine the extent to which their themes were similar or dissimilar in nature. Although previous researchers have attempted to analyze and demonstrate that these mission statements often have reoccurring themes, only limited…

This paper presents the preliminary results of a study conducted to investigate the differences in brain hemisphericity and learning styles on students' confidence in using the graphics calculator (GC) to learn mathematics. Data were collected from a sample of 44 undergraduate mathematics students in Malaysia using Brain-Dominance Questionnaire,…

This paper reports findings of a study that examined student performance and attitudes towards the use of information technology in virtual and conventional settings. Students were preservice undergraduate and graduate students enrolled in an educational media and technology course. All were fulltime, on-campus students, but one group completed…

The statistical properties of two methods of estimating gain scores for groups in quasi-experiments are compared: (1) gains in scores standardized separately for each group; and (2) analysis of covariance with estimated true pretest scores. The fan spread hypothesis is assumed for groups but not necessarily assumed for members of the groups.…

PERSONALITY TRAITS OF TEACHERS AND PRINCIPALS ARE EXAMINED FOR THEIR EFFECTS UPON TEACHER-ADMINISTRATOR RELATIONSHIPS. THE EDWARDS PERSONAL PREFERENCE SCHEDULE, THE NATIONAL PRINCIPALSHIP STUDY, AND THE ADMINISTRATIVE PREFERENCE FORM WERE ADMINISTERED TO TEACHERS AND PRINCIPALS FROM AN URBAN SCHOOL DISTRICT IN MICHIGAN. RESULTS INDICATE THAT THE…

Compares grades awarded by 5 examination boards for 11 subjects at A levels. Uses data from the A Level Information System (ALIS) project for 1989. Finds discrepancies among boards not statistically significant. Fails to identify grading as consistently severe or lenient. (NL)

The increased use of criterion-referenced statewide testing programs is an outgrowth of the need for more diagnostic information for planning and decision making than is provided by norm-referenced programs. There remains, however, a need for state agencies to compare the results of local districts to a variety of comparison groups for the purpose…

For two summers, week-long residential mathematics programs were held for high school women, with the primary goal of encouraging them to continue their study of mathematics. The activities were designed to rekindle their excitement about mathematics and to support the idea that women should learn advanced mathematics. This paper reports the…

The main aim of this study was to determine the opinions of the undergraduate students and faculty members on factors that affect student learning and academic achievement. The sub aims of this study were to: (1) Develop a mean rank ordering of the 23 dimensions affecting learning, for both the students and faculty, and determine the similarities…

Based on the assumption that inferential statistics can make the operant conditioner more sensitive to possible significant relationships, regressions models were developed to test the statistical significance between slopes and Y intercepts of the experimental and control group subjects. These results were then compared to the traditional operant…
