Professor Dr. MacLeod found something interesting - you remember things better just by saying the words aloud! Now imagine that you are skeptical and would like to replicate his study. You have three groups in your study: one group of participants reads the words silently, one group hears another person reading them aloud, and one group reads the words aloud. You then measure the number of items they can freely recall on a recall test.**This study is based on ANOVAS**The data for the 3 groups are listed below in photo. Please answer the questions directly under the data, which are questions 2-5. Please show your work and include explanations because I have trouble with these. Include the appropriate formulas (no short cuts/ short versions of the formulas please)! ThanksData and questions 2-5-

Data for the Read Silent Group (5 data points): 12, 12, 13, 14, 12 Data for the Hear Another Group (4 data points): 13, 13, 13,15 Data for the Read Aloud Group (5 data points): | | , 16, 20, 14 Recall that you will be attempting to replicate Macleod's production effect experiment. Since you are replicating the data, you decide to use a one-tailed test, with alpha = .01. 2. What scale of measurement are the independent and dependent variables of your study? Explain your answers. (2 points) Independent variable: Dependent variable: 3. What statistical test will you use to analyze your data? Explain your answer. (1 point) 4. What are the null and research hypotheses for the study? (2 points) 5. Calculate the Grand Mean (GM) for the data. (1 point)
