Confidence Interval Overlap Applet

http://wise.cgu.edu/ci_overlap/ciOverlapGuide.asp

Researchers and students alike often mistake any overlap among 95% confidence intervals to denote a statistically non-significant p value. However, confidence intervals can overlap and still correspond to a statistically significant p value for an independent sample t test. The confidence interval (CI) applet will help learners understand the relationship between confidence interval overlap and statistical significance.
