Unformatted text preview: Soc. 3204 Social Research Methods Study guide for 2 nd midterm March 18, 2007 A. Coverage Lectures and readings since the first midterm will be emphasized. Readings to focus on are Chapters 5,6, 9, Appendix B, and PP. 405 – 409. Additionally, you should know and be able to work with statistical tools that have been discussed in lab and in regular class meetings; these include the rules of percentaging, Pearson’s r, significance of r, eta, MEANS, and interpreting findings using these approaches to data analysis. The additive nature of a methods course – with new material building on earlier discussed topics -- leads me to consider the possibility of including some concepts that appeared in the earlier weeks of this course, e.g. again, the rules of percentaging, and control variable. There will not be a question about the fallacies on the upcoming midterm. B. Concepts Nominal- categories are named but not ranked. If the IV is nominal then use Eta ordinal- categories have order but the distance b/t adjacent categories is either not constant or, more likely, not known (Ribbons in a county fair). Interval- distances are known and are equal. Measurement tool is equal (not actual scores) (times, distances, heights) ratio measurement- interval scale variable with a meaningful zero point. (0 degrees K vs. 0 degrees C or 0 degrees F; Not totally absent in C or F but is in K so Kelvin is ratio) Instrument- Questionnaire- a document containing questions and other types of items designed to solicit information appropriate for the analysis. solicit information appropriate for the analysis....
