Question

An experimenter wrote an article claiming that a drug he designed is the best treatment available for pancreatic cancer. The scientific reviewing committee should confirm the experimenter’s results using A) small sample size, with a few participants and many trials. Eliminate B) small sample size, with a few participants and a few trials. C) large sample size, with a large group of participants and many trials. D) large sample size, with a large group of participants and a few trials.

Answer 1

Pretty sure it's a, because you only want a small sample size and few people. Also you want many trials because you need to know of it works. Was I right?

Answer 2

C) large sample size, with a large group of participants and many trials.

Explanation:

The context of the problem is about an experimenter who designed a drug, and he claims that is the best treatment for pancreatic cancer. However, this article can be subjective, because the experimenter is talking about himself and his achievement.

So, to prevent any type of subjectivity, a certified committee has to test this drug to demonstrate what the experimenter is claiming. The best ways to demonstrate the effectiveness of the drug is by experimenting with a large size, a large groups of participants, and with many trials. Doing this, they will experiment enough to see if the drug works or doesn't, the more trials they do using a large size, the most effective or not can the drug be.

Testing with this conditions, they will observe the drug in different kind of circumstances.

On the other hand, small sample size, small participants groups, and a few trials, cannot ensure that the drug works, because it wasn't tested enough.

Therefore, the right answer is C.
