A psychiatrist tells you that she is interested in determining ifthe condition of individuals who are clinically depressedimproves with either 20 or 40 milligrams of Prozac. She decides to administer 20 milligrams to a random half of her clients, and 40 milligrams to the other half. She finds that after 6 months, the clients who took 40 milligrams of Prozac aresignificantly less depressed than those cfients who took 20 milligrams of Prozac - Which type of study did the psychiatristconduct? A. correlational researchB. experimental researchC. controlled researchD. hypothetical research

Option B

Explanation:

In an experimental study, a hypothesis is considered rhe elated to any observation and based on that observation some conclusion is devised.

To test the hypothesis, certain variable are determined and their varied in the course of experiment to study their impact on the subject of the experiment.

Here in this research, the independent variable is "either 20 or 40 milligrams of Prozac" while the subject is "individual who is clinically depressed". After the experiment, the researcher draws a conclusion i. e "the clients who took 40 milligrams of Prozac aresignificantly less depressed than those cfients who took 20 milligrams of Prozac"

Hence, option B is correct

Experimental research.

Explanation:

The research is done to explain the particular phenomena. The research work increases the knowledge. Research is done in almost every field of the subjects.

The experimental research needs proper scientific procedure and methodology to perform the experiment. The scientific hypothesis, variable and proper calculation is done to explain the result. The psychiatrist has applied all these methods to conduct her research.

Thus, the correct answer is option (B).
