Matched sample design

Step-by-step explanation:

- A matched subject design uses separate experimental groups for each particular treatment, (A sample of brothers and sisters - genders).

- But relies upon matching every subject in one group with an equivalent in another. (The differences in ratings between each brother and sister pair were compared.)

- The idea behind this is that it reduces the chances of an influential variable skewing the results by negating it.
