Question
A researcher finds 60 people who are experiencing depression. The researcher then splits them into two groups at random. One group is given an antidepressant and the other group is given a sugar pill (but they think they are getting an antidepressant). The antidepressant would be considered the______ and the group who receives the sugar pill would be considered the ______.Group of answer choicesPlacebo/Experimental groupIndependent variable/Control group Dependent variable/Control group Independent variable/Experimental group
Solution
The antidepressant would be considered the Independent variable/Experimental group and the group who receives the sugar pill would be considered the Placebo/Control group.
Here's why:
-
Independent Variable: This is the variable that is manipulated or changed in an experiment. In this case, it's the antidepressant. The researcher is changing who gets the antidepressant and who doesn't.
-
Experimental Group: This is the group that receives the treatment or the independent variable. In this case, it's the group that is given the antidepressant.
-
Placebo: This is a substance that has no therapeutic effect, used as a control in testing new drugs. In this case, it's the sugar pill.
-
Control Group: This is the group that does not receive the treatment or the independent variable. They are used as a benchmark to compare the results of the experimental group. In this case, it's the group that is given the sugar pill.
