To evaluate the relationship between stress and general health, a researcher selects a random sample of 50-year-old men. For two months, each man is asked to keep a daily journal recording stressful events (such as a fight with his wife, an argument with his boss, or an automobile accident). After two months, a doctor examines each man and records an overall health rating. The goal of the study is to determine whether there is a relationship between the total amount of stress and overall health of men. Explain why this study is or is not an example of the experimental research strategy.
2. In a study examining the relationship between self-esteem and dishonest behavior, college students were first given a self-esteem questionnaire to classify them into high and low self-esteem groups. At a later time, cheating behavior was measured while the students corrected their own exams. The goal of the study is to find a difference between the two groups. Explain why this study is or is not an example of the experimental research strategy.
