Experimental designs-Matched pairs design

Question 1

A01

Outline matched pair designs

Answer 1

• Different P complete each condition
• P are assessed & matched on the characteristic that are important for particular research they are taking part in e.g age, ethnicity , gender
• Matched pair Participants are randomly assigned to one condition each
• Produces related data

Question 2

A03

Strenghts of Matched pair design

Answer 2

• Due to P only taking part in one condition , less likely to have order effects, cannot predict what happends next & chnage their behaviour
• Demand characteristics-less likely as P only take part in one condition , thus less likely to guess purpose of study & how to behave

Question 3

A03

Limitations of Matched pair design

Answer 3

• Matching is difficult & not possible to match all characteristics
• More P are neededs to ensure there are enough to take part in different conditions
• Time consuming
