SOCI 220 Lecture Notes - Lecture 8: Sample Size Determination
Document Summary
Quantitative: relies on numerical measurement of concepts, relies on numerical and statistical methods of data analysis and reporting, theory typically developed before data collection. Qualitative: relies on non-numerical measurement of concepts, relies on non-numerical data analysis and interpretation, theory often emerges or evolves as data are collected. 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 =
