1. A research team is interested in investigating how sleep deprivation and memory training influence memory recall (operationalized/measured by the number of words participants can remember after studying a list of words). Some participants are not permitted to sleep during the night before the study, some participants are allowed only four hours of sleep, and some participants are allowed eight hours of sleep. With reference to memory training, some participants get memory training prior to studying the word list, and some do not get memory training prior to studying the word list. Participants are randomly assigned to one of six unique groups. The research team is measuring number of words correctly recalled. Factor A is Memory Training and Factor B is Sleep Deprivation. a.) Based on the information given to you in the Question 1 research scenario, express the ANOVA design in symbols using the following format: Explain how you arrived at your answer (i.e., how you decided what values to use to fill in the blanks). X b.) Suppose we add a third factor called time-of-day to the research study described in Q1. Assume this new factor has three levels: morning, afternoon, or evening. Furthermore, Factor A is Memory Training, Factor B is Sleep Deprivation, and Factor C is Time-of-Day. Express the ANOVA design in symbols using proper ANOVA format (e.g., 4x3, 2x5, 3x2x4). Explain how you arrived at your answer (i.e., how you decided what values to use to fill in the blanks). c.) For the following ANOVA table (illustrating group means) determine whether or not there appears to be (i.) a main effect for Factor A, (ii) a main effect for Factor B, and/or (iii.) an AxB interaction effect. Explain how you arrived at your decision regarding the presence/absence of a main effect of Factor A, a main effect of Factor B, and an AxB interaction. Assume any difference between means is significant. As a reminder, Factor A is Memory Training and Factor B is Sleep Deprivation Original Study - ANOVA table No Sleep 4-hrs Sleep 8-hrs Sleep Memory Training M = 10 M = 15 M = 20 No Memory Training M=5 M = 10 M = 15
