Survey research methods: standardized set of questions (cid:862)survey(cid:863, sampling (typically involves, fairly large numbers of cases. Includes interviews, mailed questionnaires, email surveys and web surveys: tends to be quantitative ** Non-survey research methods: wide variety of different data collection methods. Labe experiments, data from other experiments, computer games/simulations: may involve some aspects of survey research, may be quantitative or qualitative ** Response rate: proportion of the sample that participates in the research: how many actually gave us useful data. Mailed questionnaires: # usable returns # sent * 100 = Interviews: #completions # attempts * 100 =
