This is a very basic lecture intended for large courses.  It provides a straightforward introduction to linear regression to students without much background in mathematics. Examples are drawn from management, and relatively heavy use is made of instant response voting technology.  Note that the color coding is intended to help students focus their attention: red is "need to know" while green is "advanced, so don't worry if it doesn't make sense."  (The first file below includes only placeholders for the IRT questions in case of compability issues, the second includes the TurningPoint slides.)

A second assignment used in an introduction to Canadian politics course. Versions of this assignment have also been used in research design and intro to US politics. This assignment builds off of the univariate assignment and requires the students to run a cross-tabulation and interpret the results (including Chi-square and measures of association). The intructions are lengthy, and designed for students to follow on their own with minimal demonstration. I used the SDA version in class, but include a SPSS version (completed by Raza Rizvi) here. The first set of questions are all multiple choice and can be grade automatically, like as a quiz on Blackboard. The latter questions allow students to choose their own variables and run an original analysis. A third assignment, requiring the students to run a t-test and/or an ANOVA will be uploaded soon. In this course, these asignments scaffolded a short public opinion bivariate research paper, but in other courses, they were a stand-alone activity.
