4. Assume that you are a health psychologist who is studying the effects of stress level on memory. You are studying two levels of stress (Low, High) and three level of task difficulty (Easy, Moderate, Hard). Subjects in the experiment are randomly selected to be placed into one of the 6 treatment groups. Then they complete a Verbal Memory task where they need to remember a list of words. Experimenters manipulate the stress level by increasing the consequences of the results. The higher the score, the more words they remembered, and thus the better they did. Raw Data given below. Each group has n =4. Factor B Task Difficulty Factor A Low Moderate High Stress Level Low 16, 18,15,17 14,12,16,156,4,4,2 High15,19,14,13 8,4,6,5 2,4,3,5 Compute the Cell Means AND Marginal Means for this 2x3 ANOVA In the space below, make a line graph showing the stress level as a function of task difficulty, with one line for stress level. Be sure to clearly label the axes and label the lines. Based on inspection of your line drawing, is there an interaction between Stress level and Task difficulty?
