SOC222H5 Lecture Notes - Venn Diagram, Causal Model, Statistical Process Control
Document Summary
1: does that relationship also exist in the population, art of finding true relationships and true causes (something you can do with, looking at causal processes, ruling out alternative explanations, causal processes, alternative explanations controlling statistically. Today"s objectives: know : how statistical control is achieved, the difference between experimental and statistical control, how to build successive regression models, the different kinds of effects when a third variable is added causal process. Terms to know alternative explanation statistical control causal diagram. Venn diagram independent effects spurious effects indirect effects interaction effects experimental control statistical control unique effect. Causal processes add a second independent variable, t: like x, it (t) is a potential cause, check covariance, and then check for effect size and significance. Causal diagrams: use arrows to show the causal connections among variables, simplest causal diagram is x. Each circle represents the variation in a variable. Indicate co-variation by overlapping or not overlapping (don"t show systematic change)
