Course Content A partially knowledgable observer could describe this course by the buzz-words "LISREL and HLM" and that concise phrase is somewhat informative. A main objective is to take a serious look at some of these advanced (and heavily marketed) statistical procedures that have become widely used (for better or worse) in education and social science. The broader perspective is to start with the data analysis (and substantive) settings that these procedures purport to address (if not solve): 1. Analysis of Multilevel Data (e.g., kids within classrooms within schools) The point being that there is much much much more to these important topics than what is covered by LISREL and HLM (programs or writings) and the challenge of organizing this course is to weave in the larger issues. |

Course Meetings 1. April 2. Because of chaos and misinformation on scheduling, the most I hope for is to assemble as many prospective students as possible and organize a real launch of the course next week. Organize, meet and greet, discuss student interests. Current Event for discussion: TV watching, aggression linked in study of teens, young adults some links: http://www.latimes.com/news/printedition/front/la-032902tv.story http://www.bayarea.com/mld/bayarea/news/nation/2959217.htm http://news.bbc.co.uk/hi/english/entertainment/tv_and_radio/newsid_1899000/1899533.stm through news.google.com I also found http://www.washingtonpost.com/wp-dyn/articles/A53840-2002Apr2.html http://canada.com/news/story.asp?id={102EB885-F812-4ABE-9DE7-C82F4D880185} http://www.philly.com/mld/inquirer/news/front/2958547.htm actual report and review in Science http://www.sciencemag.org/cgi/reprint/295/5564/2468.pdf http://www.sciencemag.org/cgi/content/full/295/5564/2377 supplementary table for the TV-aggression article is: http://www.sciencemag.org/cgi/content/full/295/5564/2468/DC1 Data Adventure #1. Multilevel school data taken from the MlWin manual. The sequence of the variables and the coding are as follows: Obtain within school regressions of normexam on standlrt (post on pre) and compare across schools. Any systematic differences for different schgend? Goldstein et al pose two substantive questions for these data under the heading of "Contextual effects" 2. April 9. 3. April 16.

If ambitious also look at the possibility of correlated erorrs in the manifest variables.

May 7. Data Adventure # 4 For the data in Adventure 1, use normexam as outcome and standirt (pretest) as precitor. Obtain directly the three regression slopes discussed in contextual analysis: total between-school, within-school pooled. Verify the Duncan-Cuzort-Duncan relationship. Verify the relations for what Kreft terms the contextual reegression model (Y on X, Xbar) and for the Cronbach model (Y on X-bar, X - Xbar).
