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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
