Correlation

Correlations determine the degree that two variables vary together, such as with the study of individual differences and job performance. The Pearson product-moment correlation coefficient or "r" is the most commonly used to measure the association of two quantitative variables characterized by a linear relationship (positive or negative). It determines how well bivariate data points stay within the assumed straight line of best fit. The correlation coefficient is a statistic or parameter which measures the strength and direction of a relationship between the two variables (Minium, King, & Bear, 1993).

Trost, Klieme, and Nauels (1998) used correlations to show the relationship between quantitative criteria for admission and performance on the First Medical Examination, thus showing the relationship between criteria for admission to medical school and student success. For their longitudinal study, data on the total population of several student cohorts admitted to medical schools (n = 28,000), was analyzed. The correlations utilized the First Medical Examination, which took place after 2-3 years of study. Criteria for admission included: 45% were admitted due to a score combining the average mark of the secondary school leaving certificate and results of a specific scholastic aptitude test (the Test fo

ge. Sample sizes ranged from 60 and 83 randomly chosen PD graduates and between 86 and 205 randomly chosen traditional program graduates; these students were taken from those who completed the programs. There were several hypotheses for this study, researching findings related to instructional processes, declarative knowledge, intellectual skills, tolerance for ambiguity, and attitudes toward instruction. The first hypothesis, which utilized the t-test, predicted that PD courses would contain more field projects and cases, more group work, and more presentations compared to the traditional program courses; data was from PD and traditional course syllabi. The t-test was used to analyze this prediction. Other tests were used for the remaining hypotheses. Results of the t-test showed a comparison of percentages of points which were allocated to field projects and cases, versus structured examinations and quizzes in the core PD, compared to the traditional program syllabi. Findings revealed that core PD courses weighted field projects and cases more heavily with t = 6.0, p < .001. and traditional program courses weighted structured examinations and quizzes more heavily with t = 5.7, p < .001. Thus extrinsic incentives in the
