Less materials needed

Matched pairs is where different participants are used fro each condition, however they are matched based on variables such as age, gender, and so on which they are pre-tested on.
Positives of matched pairs:

No order effects
Less chance of demand charcteristics
Negatives of matched pairs:
Matching is difficult
More pariticipants needed
Time consuming
Repeated measures are where each participant takes part in both conditions and their perfomace is compared
Positives of repeated measures:
