In medicine and psychology, clinical significance is the practical importance of a treatment effect-whether it has a real genuine, palpable, noticeable effect on daily life.

A level of significance is selected (most commonly α . 5 or . 1), which signifies the probability of incorrectly rejecting a true null hypothesis.
Before you answer, first let me clarify something: Clinical significance is the practical importance of the treatment effect, whether it has a real, palpable, noticeable effect on daily life. For example, imagine a safe treatment that could reduce the number of hours you suffered with flu-like symptoms from 72 hours to 10 hours. This is the same topic on which i am working. we all get carried away by the p value least realizing the importance of clinical or practical significance. April 23, 2017 at 1:33 pm Reply to Pradnya.
