PSY 230 Lecture Notes - Lecture 2: Logistic Regression, Discriminant Function Analysis, Cluster Analysis
Document Summary
Gender: dependent variable: response measure that we think will be influenced by the iv, moderating variables: influence the relationship btwn iv and dv, mediating variables: variables that intervene btwn iv and dv in their cause-effect relationship. The method section: details about exactly how the variables were measured, manipulated, and controlled: participants/subjects: humans/animals that participated in the research, materials/apparatus: details about equipment, tests, etc, procedure: chronological sequence of what happened to the participants. The discussion: where the author describes how the results fit into the literature. T-test: used to compare means of 2 groups. F-test: used to compare means of more than 2 groups. Pearson"s r-test: used to investigate whether there is a linear relationship between 2 continuous variables. Regression: use a predictor variable to predict a criterion variable: multiple regression: using more than one predictor variable to predict a criterion variable.
