Answer 5

condition

Question 6

A factorial design that uses the same participants for each condition

Answer 6

within-subject design

Question 7

a factorial design that uses different participants for each condition

Answer 7

between-subject design

Question 8

A factorial design that includes at least one between-subject variable and one within-subject variable

Answer 8

mixed-factorial design

Question 9

Why use factorial designs?

Answer 9

1. Examine the effect of multiple variables at once
2. In real life multiple variables interact together
3. Examining interactions between independent variables
4. finding moderator variables
5. efficient
6. cheeper

Question 10

The independent variable that has an overall effect on a dependant variable

Answer 10

main effect

Question 11

When the independent variable influences a dependant variable differs depending on another independent variable

Answer 11

interaction effect

Question 12

A variable that alters the strength or direction of a correlation

Answer 12

moderator variable

Question 13

Limitations of factorial designs

Answer 13

1. the total number of conditions might be too large to control
2. Takes longer to conduct

Question 14

A representative statistic for the average

Answer 14

cell mean

Question 15

Analysis for dependant variables on an interval or ratio scale

Answer 15

ANOVA, analysis of variance

Question 16

The effect of one independent variable at a particular level of another independent variable

Answer 16

simple main effect

Question 17

tests that are conducted after initial findings

Answer 17

post-hoc tests

Question 18

Order of tests conducted

Answer 18

ANOVA - test of simple main effects - post-hoc comparisons

Question 19

variables that are characteristics of the participants

Answer 19

subject variables

Question 20

How a participant reacts depending on the situation

Answer 20

situational factor

Question 21

An experimental design that uses one subject variable and one situational variable

Answer 21

person x situation factorial design

Question 22

quasi-independent variables

Answer 22

variables that cannot be manipulated but can distinguish different groups

Question 23

When two independent effect each other which influences the dependent variable

Answer 23

two-way interactions

Question 24

when two independent variables in fluence a third

Answer 24

three-way interaction

Question 27

When each sequence comes only once, but requires an even number of levels

Answer 27

balanced latin sequence
