Question 3

matched pairs design

Answer 3

pairs of participants are matched in terms of key variables/characteristics.
One member of each pair is then placed into the experimental group and the other member into the control group

Question 4

Ads of repeated measures

Answer 4

Needs half amount of ppn compared to IG
Ppn variables not a problem
Related data

Question 5

Disadvantages of repeated measures

Answer 5

MORE LIKELY TO WORK OUT THE AIM - DC
Order effects (1st condition influences the behaviour for 2nd)

Question 6

Counter balancing

Answer 6

ABBA (each group does the conditions opp ways round to CONTROL (not eliminate) order effects

Question 7

Independent group design ads

Answer 7

Less likely to work out aim -dc
No order effects

Question 8

Independent group design dis

Answer 8

Need double ppn to RM

Unrelated data - cant be paired

Question 9

Matched pairs ads

Answer 9

Related data, reduced ppn variables, no order effects

Question 10

Matched pairs dif

Answer 10

Takes longer
Needs double ppn to RM
Ppn are similar not identical so cna have ppn variables
