experimental design

Question 1

what is matched pairs design

Answer 1

pairs matched on variables that may affect DV
each member is randomly allocated to each condition

Question 2

strength of matched pairs

Answer 2

no order effects

Question 3

3 limitations of matched pairs

Answer 3

-large pool of potential participants needed- hard to get
-time consuming
-hard to know which variables are appropriate for participants to be matched

Question 4

what is independent groups design

Answer 4

participants only experience one condition of the IV

Question 5

2 strengths of independent groups

Answer 5

-participants less likely to guess the aims of the study
-eliminates demand characteristics

Question 6

2 limitations of independent groups

Answer 6

-no control over participant variables- different abilities of participants in the various conditions can cause changes to DV
-more participants needed to gather sufficient data

Question 7

what is repeated measures design

Answer 7

all participants experience all conditions of IV

Question 8

2 strengths of repeated measures

Answer 8

-eliminates participant variables
-fewer participants needed so not as time-consuming

Question 9

limitation of repeated measures

Answer 9

order effects
