factorial designs

Question 1

when is a mixed design used

Answer 1

when one factor is expected to threaten validity

Question 2

repeating the previous study by using the same factor or IV
exactly as it was used in the earlier study

Answer 2

replication

Question 3

adding a second factor in the form of new conditions or new
participant characteristics

Answer 3

expansion

Question 4

true or false: replication is used to ascertain whether previously reported effects can be generalized to new situations or new populations

Answer 4

false, this describes expansion

Question 5

how do you reduce variance in a between subjects factorial design

Answer 5

you can use the participant variable as its own factor in order to reduce individual differences

Question 6

how can you reduce order effects in a within subjects factorial design

Answer 6

you can use the order of treatments as a second factor

Question 7

what are the three possible outcomes that can occur from using the order of treatments as a factor

Answer 7

you can have either no order effects, symmetrical order effects, or nonsymmetrical order effects
