Detailed explanation-1: -A matched pairs design is a type of experimental design wherein study participants are matched based on key variables, or shared characteristics, relevant to the topic of the study. Then, one member of each pair is placed into the control group while the other is placed in the experimental group.

Detailed explanation-2: -Four major design types with relevance to user research are experimental, quasi-experimental, correlational and single subject. These research designs proceed from a level of high validity and generalizability to ones with lower validity and generalizability.

Detailed explanation-3: -"A matched pairs design is a special case of a randomized block design. It can be used when the experiment has only two treatment conditions; and subjects can be grouped into pairs, based on some blocking variable. Then, within each pair, subjects are randomly assigned to different treatments."

Detailed explanation-4: -Example of a Matched Pairs Design They recruit 100 subjects, then group the subjects into 50 pairs based on their age and gender. For example: What is this? A 25-year-old male will be paired with another 25-year-old male, since they “match” in terms of age and gender.
