5 Multiple choice questions
- the characteristics of the random sample are different from the characteristics of the entire population, when the sample size is too small, and when the sample is not homogeneous. validity decreases. non response is a problem
- validity of generalized statements based on limited research studies, or implications. usually when a study in a lab is moved out of the lab causes problems, or a small ground finding in ny, can differ from ca
- survey method that includes all of the members of a population. no sampling procedures and no generalizability issues
- extent to which the research really studied what it was supposed to. did it find out what it was trying to?
- determined based on the return rate of target pop, and the value of the info provided by the respondent. is that value of the info you recieve worth the cost?
