Detailed explanation-1: -Matched Pairs Design The tailored participant-matching process reduces the risk of participant variables (individual differences) from affecting results between conditions. Different participants need to be recruited for each condition, which is difficult and expensive.

Detailed explanation-2: -With the use of the matched pairs design, researchers can improve the comparability of their study participants despite their smaller sample size, increasing the validity of the cause-and-effect relationship identified in the experiment.

Detailed explanation-3: -A matched group design is an experimental design where the participants in the study are chosen because they have variables that match each other. The variables can be anything that might affect the results of the study, for example, height, weight, age, etc.

Detailed explanation-4: -A matched pairs design allows us to randomize subjects better. A matched pairs design allows us to get more data points. A matched pairs design reduces inherent bias from the people conducting the experiment.
