Assignment:

You are asked to design an evaluation of the following hypothetical scenario. Use the Hoover text as well as the Research Methods Knowledge Base, drawing on the concepts of correlational designs, experimental designs, quasi-experimental designs, time series designs, non-equivalent groups (you do not need to use ALL of these, but you do need to pick one and explain why you have made this choice. This would be a good time to start reading the sections on the types of research design, highlighted in Week 7 of the syllabus).

'Heartbreak fatal, researcher claims' is the headline of a newspaper story that says that the stress from severe emotional trauma can lead to heart failure. The findings are based on a study of six heart patients who suffered symptoms such as fainting and irregular heartbeat but showed no evidence of heart defects or disease. All six, however, had experienced severe emotional trauma. This study also shows the episodes responded favorably to certain drugs such as beta blockers.

Part A). Critique this study: What would you change about this study? Is this a strong design? Why/Why not?

Part B). Design a correlational study to test this hypothesis: "Heartbreaks are fatal." (Remember, a correlational study is quite different from an experimental study; you are expected to know the difference in order to set this study up in the correct manner).

Part C). Design a quasi-experimental or experimental (these are different, and you have to explain to me specifically why your study is one versus the other) study to test the hypothesis: "Beta blockers are effective in treating heartbreak episodes."
