PSYB01H3 Lecture Notes - Lecture 9: Repeated Measures Design, Complement Factor B
Document Summary
Week 11 lecture #9 monday, july 20, 2015. Level 1: low, level 2: high, level 3: low, System that simultaneously identifies the number of iv and the number of levels of each. Number of levels number of levels of of first iv. Look at all possible combinations of the different levels of each iv. 2-sec/word 4-sec/word imagery/2 sec imagery/4 sec rote/2 sec rote/ 4 sec. Number of conditions can be determined by calculating the product of the numbers in the notation system. 2 x 2 x 4 = 16. The overall effect of a single iv. So in a study with 2 iv, there can be at most 2 main effects. Determining the main effect for one iv involves combining all the data for each of the levels of that factor. Interactions: when the effect of one iv depends on the level of another iv. Main effect of presentation rate (imagery and role)
