Measures of variability and precision in statistics: appreciating, untangling and applying concepts.

Adam Ciarleglio1.   

Abstract

This reflection presents a discussion of some common measures of variability and how they are appropriately used in descriptive and inferential statistical analyses. We argue that confidence intervals (CIs), which incorporate these measures, serve as tools to assess both clinical and statistical significance.
