Summer 16 PSYB07 Assignment Professor Isaiah was interested in investigating if students' test scores differ based on the time of day his lectures were being held. He selected a sample of 15 students from his morning (n = 7) and evening (n = 8) Psychology classes and recorded their midterm and final exam scores as shown below. 1. He was interested in examining whether students in his morning class performed better compared to students in his evening classes on their final exam scores. Does the data support Isaiah's hypothesis? [30 points] 2. Professor Lisa-Marie, a colleague of Isaiah's, suggested that 'exam type' (Midterm vs. Final) might also be a factor in exam performance. Specifically, she predicted students attending the morning class would perform worse on the on the final exam compared to the midterm. Does the data support Lisa-Marie's hypothesis? [30 points] 3. The two professors predicted that there would be a positive relationship between the midterm and final exam grades for the evening class. Was there evidence to support this prediction? [30 points] 4. Finally, using your actual midterm mark, what would Isaiah & Lisa-Marie predict your final exam mark to be if you were enrolled in the evening class? (of course many other factors go into your final exam mark, so let's see how accurate this prediction ends up being :) [10 points] Bonus: Based on all of the above findings, how might Isaiah & Lisa-Marie change (or keep the same) their courses next term? Why?
