Question

A new medication was developed to decrease the blood pressure of an individual. An experiment was conducted to the test the effectiveness of this new medication. In a sample of 50 subjects, each person's blood pressure was measured prior to taking the medication. Two weeks after taking the medication, the blood pressure was measured again, and a comparison was made between the measurements before and after taking the medication. What type of experimental design is being used?

Answer 1

The experiment to test the new medication's effect on blood pressure employs a pre-test/post-test design, where subjects' measurements are compared before and after treatment.

Step-by-step explanation:

The type of experimental design being used to test the effectiveness of a new medication that claims to decrease blood pressure is known as a pre-test/post-test design. In this experiment, each subject's blood pressure is measured before and after the application of the treatment, allowing for direct before-and-after comparisons within the same group of individuals. This design helps in assessing the impact of the medication on the blood pressure of the subjects.
