It’s the night before an exam and the existential crisis faced is “To sleep or not sleep?” Gillen-O’Neel et al (2012), reported “that regardless of how much a student generally studies each day, if that student sacrifices sleep time to study more than usual, he or she will have more trouble understanding material taught in class and be more likely to struggle on an assignment or test the following day.” A Professor in an Educational Psychology class attempted to replicate a portion of Gillen-O’Neel et al’s (2012) study. The professor recorded a significant difference in the class performance between Exam 1 and Exam 2; and collected information from a sample of 25 of the course’s students on their self-reported hours slept before Exam 1 and Exam 2. The following reported hours were analyzed to determine if there was a significant difference in the hours slept before the two exams. Ex 1: 7, 8, 5, 6, 6, 7, 3, 5, 8, 7, 8, 9, 6, 7, 9, 5, 8, 9, 7, 6, 3, 5, 3, 6, 9. Ex 2: 6, 5, 8, 9, 9, 8, 7, 7, 6, 9, 8, 8, 9, 9, 8, 6, 9, 6, 8, 7, 6, 8, 8, 8, 4. Requirements: a. Independent variable: Exam 1 vs Exam 2_____________ b. Dependent variable: Hours Students Slept_______________ c. Hypotheses (Symbols): H0: μ1 = μ2; H1: μ1 ≠μ2 d. What is the correct t-test: Pair Sample t-test One-tailed or two-tailed? Two-Tailed e. tcrit = 2.064 f. Instructions: Enter the data into Excel and save as a .CSV file. Run the analysis using JASP to test if there is a significant difference between the sleep times for Exams 1 and 2, INCLUDE the t-test output. Was the data normally distributed? g. Use APA style, to report findings using the variables in the study (including Cohen’s d). h. Use APA style to report the results if you had predicted that Exam 1 hours would be significantly less than Exam 2.
