Question

A medical researcher tested a new treatment for poison lvy against the traditional ointment. He concluded that the new treatment is more effective. Explain what the P-value of 0.076 means in this context. Explain what the P value of 0.076 means in this context. A If there is a difference in effectiveness, the chance of seeing an observed difference this large or larger is 7.6% by natural sampling variation. B. There is a 7.6% chance that the new treatment is effective. C. H there is no difference in effectiveness, the chance of seeing an observed difference this large or larger is 7.6% by natural sampling variation. D. There is a 7.6% difference between the effectiveness of the new treatment and the effectiveness of the traditional ointment.

Explanation / Answer

Meaning of P value in research: P value of k suggest that there is (100*k) % chance that the results of study occurred by chance alone.

So here P value of 0.076 means that there is 7.6% chance that the new treatment is effective only by chance.

In other words, we can say that "if there is no difference in effectiveness, the chance of seeing an observed difference this or larger is 7.6% by natural selection". Option C
