Chapter 7 experimental design- factorial designs

Question 1

Factorial design

Answer 1

any experimental design with more than one IV

Question 2

Factorial design matrix

Answer 2

a row and column arrangement that characterises a factorial design and shows the IV’s, the level of each IV and the total number of conditions in the study

Question 3

main effect

Answer 3

the presence of otherwise statistically significant differences between levels of an IV in a factorial design

Question 4

interaction

Answer 4

in a factorial design, an interaction occurs when the effect of one IV depends on the level of another IV

Question 5

mixed factorial design

Answer 5

a factorial design with at least one between-subjects factor and one within subject factor

Question 6

P X E Factorial designs

Answer 6

personal variable, environmental variable

Question 7

mixed P X E Factorial design

Answer 7

a mixed design with at least one subject factor and one manipulated factor

Question 8

ATI Designs

Answer 8

aptitude treatment interaction design- form of P X E Factorial design that is found in educational research, the goal of which is to examine possible interactions between aptitude variable and treatment variable

Question 9

Simple effect analysis

Answer 9

following an ANOVA, this is a follow up test to a significant interaction, to compare individual cells
