Matched pairs design is where participants are grouped through the coupling of participants from similar attributes such as age, height, interests etc
Matched random samplingEdit
A method of assigning participants to groups in which pairs of participants are first matched on some characteristic and then individually assigned randomly to groups.
The procedure for matched random sampling can be briefed with the following contexts,
- Two samples in which the members are clearly paired, or are matched explicitly by the researcher. For example, IQ measurements or pairs of identical twins.
- Those samples in which the same attribute, or variable, is measured twice on each subject, under different circumstances. Commonly called repeated measures. Examples include the times of a group of athletes for 1500m before and after a week of special training; the milk yields of cows before and after being fed a particular diet.
