Question

A research design where each participant in one group is matched or paired with a different but assumed equivalent participant in a second group is called a:

a. Repeated measures design
b. Matched-pairs design

Answer 1

A research design where each participant in one group is matched or paired with a different but assumed equivalent participant in a second group is called a Matched-pairs design. This design helps minimize the effects of individual differences and improve the internal validity of the study.

Step-by-step explanation:

A research design where each participant in one group is matched or paired with a different but assumed equivalent participant in a second group is called a Matched-pairs design. In this design, participants are selected based on certain characteristics or variables that are expected to be similar between the two groups. This type of design is often used to minimize the effects of individual differences and enhance the internal validity of the study.
