Misbeliefs and Preconceptions Regarding P- Value
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 6
Abstract
The medical journals are abounding with „P values‟ and „tests of hypotheses. It is a common practice among medical researchers to quote whether the „test of hypothesis‟ they carried out is significant or nonsignificant and many researchers get very enthusiastic when they discover a “statistically significant” finding without really understanding what it means.Additionally, while medical journals are florid with statement such as: “statistical significant”, “unlikely due to chance”, “not significant,” “due to chance”, or notations such as, “P > 0.05”, “P < 0.05”, the decision on whether to decide a „test of hypothesis‟ is significant or not based on P value has generated an intense debate among statisticians. The P value is probably the most ubiquitous and at the same time, misunderstood, misinterpreted, and occasionally miscalculated index.
