Dr. wong is working on a better treatment for ringworm, a fungus that infects the surface of the skin. current treatments require the application of a cream and/or the ingestion of medication for as long as three months.

dr. wong thinks that he has developed a cream that can cure ringworm in no more than three days. what is the best way for dr. wong to be more certain that his experimental results are not biased?

a. dr. wong could publish his data in a scientific journal and have different investigators try to reproduce his results.

b. dr. wong could have one of his assistants perform one additional experimental trial and see if the results are the same.

c. dr. wong could hide his data when publishing his results, so others will not be able to replicate his experiments.

d. dr. wong could reduce his sample size, so he only focuses on a few select cases of ringworm.

The correct answer is a) Dr. Wong could publish his data in a scientific journal and have different investigators try to reproduce his results. This is due to external validity, when data from a research can be confirm and reproduced, after selecting a proper sample size and determine alfa and beta power, for the study. If no bias exists, other researchers should be able to replicate and validate Dr’s Wong Results.

B and C options are both unacceptable due to ethical issues, and D is incorrect based on the central limit theorem; if Dr’s Wong sample is at least 30 in number (for each group: A=test group and B=control group) the statistical inferences can be translated into larger populations. Smaller samples than this, are not recommended due to bias and internal validity.

The correct answer is a) Dr. Wong could publish his data in a scientific journal and have different investigators try to reproduce his results.
