Sandy wants to know whether men are more jealous than women. She asks 400 college students a series of questions about real-life scenarios of partner cheating. She operationalizes "jealousy" as partner-directed actions of yelling, hitting, or throwing/breaking objects. What is the confound in Sandy's study?
1. Her idea of jealous behavior was not clearly defined.
2. Her sample's attitudes may not accurately represent her population's attitudes.
3. Her sample is not large enough to yield a statistically valid conclusion.
(Notes: I found this Question at Chegg and the answers there gave me confusion)
