HW 3 Directions ANCOVA Assume that you are comparing performance in a statistics class taught by two different methods. Students in one class are instructed in the classroom, while students in the second class take their class online. Both classes are taught by the same instructor, and use the same textbook, exams, and assignments. At the beginning of the term all students take a test of quantitative ability (pretest), and at the end, their score on the final exam is recorded (posttest). Because the two classes are intact, it is not possible to achieve experimental control, so this is a quasi-experimental design. Assume that you would like to compare the scores for the two groups on the final score while controlling for initial quantitative ability. The data are saved in the file "HW 3 Data.sav". The data set is organized according to its "Code Book" below: HW 3 Data.sav Variable Name Variable label Value Labels Participant Identification number of participants Pretest Measure of initial quantitative ability (covariate) Posttest End of term quantitative performance (dependent variable) Method In class or online (independent variable) 1 = in class; 2 = online The independent variable is "Method" (coded 1 or 2).
