Here's a link to a wiki articcle that will get you started (LINK)... “Statistically significant” means a result is unlikely due to chance. The p-value is the probability of obtaining the difference we saw from a sample (or a larger one) if …

**Tests of Statistical Significance**

Interpretation: Not a statistically significant or clinically significant result. P.S. Answer to CI question about weight loss: The CI of 2-18 for the weight loss example is a wide interval and the study should be repeated with a larger sample size to get the CI closer to the population mean.... Even though the WHI Subgroup Hazard Ratios differ from 1.0, they are not statistically significant when the confidence intervals include 1.0. For instance, although a possible reduction in breast cancer risk with estrogen is reported in the estrogen-only arm (HR= 0.77), this is not statistically significant (CI = [0.59- …

**The Relationship between Confidence Intervals and**

A difference of 3% (58% for women minus 55% for men) can be statistically significant if the sample size is big enough, but it may not be practically significant. Three percent hardly seems big enough to warrant focusing on one market over the other. how to make hair tinsel stay longer Even though the WHI Subgroup Hazard Ratios differ from 1.0, they are not statistically significant when the confidence intervals include 1.0.
