A Confidence Interval Visualizes The Variability Of A Point Estimate At A Certain Level By Producing One Or Two Bounds Expressed In Terms Of Possible Effect Sizes.

Confidence intervals (cis) are widely used in reporting statistical analyses of research data, and are usually considered to be more informative than p values from significance tests.1 2 some published articles, however, report estimated effects and p values, but do not give cis (a practice bmj now strongly discourages). It can thus be viewed as a. The p value is calculated only after assuming that the null hypothesis is correct;

There Are No Fixed Answers, And Other Studies Are Required.
