PSYC 2230 Lecture Notes - Lecture 9: Complement Factor B, F-Test, Dependent And Independent Variables
Document Summary
Exam: focus on articles in textbook (case studies) know the purpose of the study, what the experimenter did and concluded, 78 questions, 4 choices. Overview of complex/factorial designs: main effect and interaction effect. Researchers often investigate the effects of two or more ivs simultaneously. All levels of each iv are combined with all levels of the other iv"s. Complexity relies on how the factorial is constructed. 2 x 2 design (described by number of variables and by how many levels each variable has) so in this case it is two variables with two conditions. First iv factor a: type of question level 1: misleading and level 2: unbiased. Factor b: knowledge of the crime level 1: naive question level 2: knowledgeable questioner. Dependent: whether they convict or let the suspects go. It can be modified: by increasing the levels of an iv such as 3 x 2 = 2 iv"s one with 3 levels and the other with 2 levels.
