A researcher conducted an experiment to assess the influence of preparation on high school juniors' composite SAT scores. At the beginning of students' junior year, they were enrolled in an SAT prep course as part of their regular high school schedule and provided with laptop computers to use in the class and at home. Each student was randomly assigned to one of three sections of the course. In the section the researcher referred to as "Group A," students were enrolled in the Khan Academy SAT prep course and encouraged to proceed through the course at their own pace. The teacher proctored class sessions and provided tech support but no instruction in SAT test strategies. Students in "Group B" were also enrolled in the Khan Academy course, but the teacher provided group instruction in SAT test strategies during class meetings. Like students in the other two groups, those in "Group C" were enrolled in the Khan Academy course. Their first assignment was to complete a diagnostic test. Based on the test results, each student was assigned to an individualized study program that included weekly one-on-one tutoring sessions that were delivered virtually at a time of the student's choosing. Students' first tutoring session was devoted to developing a personal score goal based on their diagnostic results and test score data from colleges they were interested in attending. During class sessions, Group C students worked independently on their laptops and received no help other than tech support from the teacher. If students had questions or problems between tutoring sessions, they were encouraged to message their tutors during class or at any other time they chose. The researcher also hypothesized that variables other than formal test prep would be related to students' SAT scores. She predicted that math achievement, as represented by students' junior year math courses, would be related to their SAT scores and might interact with the type of test prep instruction they received. *Data Analysis Project 2 D...
