Document Summary
Chapter 4: alternatives to experimentation: surveys and interviews. Two most common types of surveys: written questionnaires: handed out or sent through mail. Interviews: face-to-face or on the phone; in person interviews can be individual or group. * generalizability of surveys depends on how subjects were selected. >divide those responses in categories (someone said something to me, someone looked at me funny, etc) * tips for constructing questions: keep it simple and keep people involved. -> you like strawberries but not ice cream so you could not answer this question. Continuous dimension: when variables lend themselves to different levels of measurement; traits, attitudes, and preferences are all continuous; ex: trait of sociability can range from very unsociable to very sociable (each person falls somewhere on that dimension) *when selecting a level of measurement that all fit equally well, choose the highest level possible because it provides more information about the response)*
