Question

In an experiment to test a new drug’s effectiveness, one group is given a larger dosage than is typically prescribed, and a second group is given a smaller dosage than is typically prescribed. Then, the results of the groups are compared to each other. What is missing that would improve this scientific design? A. control group B. reliant variable C. dependent variable D. independent variable

Answer 1

I think the correct answer from the choices listed above is option A. A control group is missing that would improve the scientific design. This control group should be done at a regular dosage prescribed. This is important to minimize errors in the experiment.

Answer 2

i believe it's a because rnt the two different medicines the dependent and independent and then u would need a control group that would stay the same.
