December 30, 2013

Statistic significance, also known as p-value, and CI (Confidence Interval) are common statistics measures and are major at the statistical analysis of studies in medicine and life sciences. These measures provide complementary information about the statistical probability and conclusions regarding the clinical significance of study’s findings. This article is intended to describe the methodology of the methods, compare between the methods, assert their suitability for different needs of study results analysis and explain situations in which each method should be used.
