Answer 1

• Two groups of people are used to test the effects of a particular factor
• Each individual is paired with another individual who has everything in common with them except for the factor being studied

Answer 2

Advantages:

Eliminates all extraneous factors

Disadvantages:

Might need to sample a lot of people to find a matched pair
