- 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

5 True/False questions
sampling unit → 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
simple induction → future conclusion from some sample in the past
nonprobability (non scientific) samples → each member does not have a known chance of being selected, researcher randomly chooses sampling units. inexpensive and easy. used for questionnaire testing and prelime stages
email survey → database and html, can skip to certain questions based on answer and wont let respondent skip. can provide animation. more complicated to design than email. fast, low cost, flexible. population sample limitation
inductive analogies → similarities between two things to a conclusion about some additional attribution of both things.
