|
Two separate groups of participants experience two different conditions of the experiment.
|
|
|
All participants experience both conditions of the experiment-the experimental condition and the control condition.
|
|
|
Participants are paired together based upon a variable/variables relevant to the experiment.
|
|
|
None of the above

Detailed explanation-1: -Repeated Measures design is an experimental design where the same participants take part in each condition of the independent variable. This means that each condition of the experiment includes the same group of participants. Repeated Measures design is also known as within groups, or within-subjects design.
Detailed explanation-2: -A repeated-measures design is one in which multiple, or repeated, measurements are made on each experimental unit. The experimental unit could be a person or an animal, and repeated measurements might be taken serially in time, such as in weekly systolic blood pressures or monthly weights.
Detailed explanation-3: -Repeated measures design is a research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods. For instance, repeated measurements are collected in a longitudinal study in which change over time is assessed.
Detailed explanation-4: -An example of repeated measures design for medical research would involve choosing five participants and testing them for their response to three different cancer drugs. Each participant in the study would try all three drugs and be evaluated after each one.
Detailed explanation-5: -It’s still a true experiment, because we can look at performance in a particular condition and compare it to performance in another condition, with the only thing that differed between conditions being the experimental manipulation. There is still randomization in a repeated-measures design.
