Few meaningful sex differences will be reported if investigators go beyond the reporting of statistical significance to determine the indices of experimental effect size. Techniques for obtaining this type of information include the calculation of d and the estimate of omega squared, which indicate the advisability of continuing a line of…

The purpose of this study was to combine knowledge of teacher demographic data with time-series forecasting methods to predict teacher turnover. Moving averages and exponential smoothing were used to forecast discrete time series. The study used data collected from the 22 largest school districts in Iowa, designated as FACT schools. Predictions…

This study stems from attempts to develop prediction equations for freshman grade point average for two demographic classifications of students at a southwestern university. Although the particular results are probably of interest only to that university, certain aspects of the study should be of general interest, because, of the 3,237 students…

Validation of an Air Force vocational interest inventory in the enlisted force was conducted to develop improved job placement techniques with a view toward practical application of results during initial counseling and job placement of enlisted personnel. The Vocational Interest-Career Examination (VOICE) was administered to 18,000 recruits…

The stability and change of verbal, non-verbal, and total IQ scores from group tests were investigated for students tested at Grades 1, 2, 4, 7, 9, and 11. Conclusions are discussed in detail, and the following recommendations are made: (1) Group intelligence tests should not be routinely administered in Grades 1 and 2 unless the users and…

This report presents quantitative data from an ongoing longitudinal study, the Cooperative Institutional Research Program, on degree attainment rates at institutions of higher education. The report covers national degree completion data for three time intervals--4, 6, and 9 years--broken down by institutional type, student gender, and student…

The criterion-oriented problem of test bias and fairness in selection is compared to the construct-oriented problem of comparability of test scores in cross-cultural research. These problems are shown to have important similarities, and their studies may supplement each other. In a formulation of psychometric criteria for the comparability of test…
