Vanessa is planning on conducting a study that looks into how listening to music impacts learning. Specifically, she wants to know how well people can learn while listening to their favorite, or least favorite, type of music. For her study, she has all participants study a list of words (for 20 minutes) while listening to music. Half of the participants study the list while listening to their favorite music. The other half study the list while listening to their least favorite music. Then, all participants receive a memory test in which they try to recall as many words from the list as they can. Finally, Vanessa will compare the memory test performance of the groups. Use this information to answer the questions below about Vanessa's planned study. Please number your answers. 1. What is the independent variable and its levels? What is the dependent variable? (4 points) 2. Identify the design of study. Explain your answer. (2 points) 3. What are two possible confounds in this study? And, explain how they could influence the results and how they could be minimized/eliminated. (4 points) 4. Vanessa plans on using an independent samples t-test to analyze her data. What are the assumptions she needs to meet in order to conduct that test? And how would she check she meets each of those assumptions? Be specific. (5 points) 5. Give a description of a different type of design Vanessa can use to answer her research question. What is a benefit and a limitation of this design? Be specific. (5 points)
