Suppose you are interested in the effects on boys of different dosages of a new drug to treat ADHD. You set up an experiment to
consider the factor of dosage with two levels (300 mg vs. 500 mg). Which would be the best choice for the different treatment groups of the experiment within each block?
it would be ideal to split the test into 4 different groups
Explanation:
To better test the effects of the drug at different doses, it is important to consider the standard of the scientific method in testing.
Control testing is important in the first group of patients to take no drugs, in the second group of patients taking a placebo, in the third group of patients taking a 300 mg dose of the drug, and finally in the fourth group one dose of 500 mg. This wide range of doses and placebos not only shows better data, but creates a basis for better comparison of the final results.
