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: -A matched pairs design is a type of experimental design wherein study participants are matched based on key variables, or shared characteristics, relevant to the topic of the study. Then, one member of each pair is placed into the control group while the other is placed in the experimental group.
Detailed explanation-2: -Matched pairs design is an experimental design where pairs of participants are matched in terms of key variables, such as age and IQ. One member of each pair is then placed into the experimental group and the other member into the control group.
Detailed explanation-3: -Example of a Matched Pairs Design They recruit 100 subjects, then group the subjects into 50 pairs based on their age and gender. For example: What is this? A 25-year-old male will be paired with another 25-year-old male, since they “match” in terms of age and gender.
Detailed explanation-4: -A matched group design is an experimental design where the participants in the study are chosen because they have variables that match each other. The variables can be anything that might affect the results of the study, for example, height, weight, age, etc.
Detailed explanation-5: -A matched-pairs design only works with two treatment conditions, or circumstances that might make a difference in a study. For example, in Professor Stephens’ experiment, the two treatment conditions would be paper-based homework and computer-based homework.
