You are sitting with a group of friends and someone brings up the old saying “opposites attract”. Someone says, “I wonder if that’s really true, though”. And then your friend says, “It’s definitely true. My grandparents have nothing in common, but they’ve been happily married for 60 years!”
A) Design a study to test the idea that opposites attract (9 points).
1. Define “operational definition” and identify each of the operational definitions on your study.
2. Explain how we can distinguish an experimental study from a nonexperimental study. Which type of study is yours?
3. Given the type of study you are conducting, will you be able to draw causal inferences from your results? Why or why not?
B) Explain the difference between internal and external validity. Which type does your study prioritize? (3 points)
The remaining 3 points will be based on writing quality.
