Q

Define matched pair design

A

Pairs of participants are matched in terms of key, relevant variables. One member of each pair is allocated to one condition and the other is allocated to the other condition.

Q

Limitations of repeated measures design

What are these called?

A

Q

How to deal with repeated measures limitations?

How to reduce practise effects?

A

Counterbalancing ensures that each condition is tested first or second equal amounts.

Use two different, but equivalent, tests to reduce a practise effect
