Multiple choice question

Intervention in a research experiment means manipulating or influencing some of the variables that affect a situation. The purpose of an intervention is to let researchers examine what happens in groups that are exposed to an intervention or treatment (experimental groups). Groups that are not exposed to the intervention or treatment are called control groups. Exposing only some participants to an intervention enables the researchers to examine what happens when people in the experimental group are exposed to the intervention, in comparison to people in the control group who are not exposed to the intervention.

Read the paragraph and answer the question below.

The people in the control group benefit from the intervention.

The people in the experimental group are exposed to the intervention.

Designing Experiments

 

If researchers want to test whether a new medical treatment is effective, they design an experiment. They divide the people who take part in the experiment into 2 groups: One group gets the new medicine and the other group does not. Giving one group the new medicine is called an intervention. The group that is exposed to the intervention is called the experimental group. The group which is not exposed to the intervention is called the control group.

According to the information in the paragraph, which answer below is correct?

Choose the ONE correct answer. 

Response:

The people in the experimental group are exposed to the intervention.
