I actually created this design more than two years ago. I was rummaging through some old statistics books and remember how everything was expressed within given confidence levels. If you're into statistics, a confidence interval is a particular kind of interval estimate of a population parameter. Instead of estimating the parameter by a single value, an interval likely to include the parameter is given. Thus, confidence intervals are used to indicate the reliability of an estimate and is always qualified by a particular confidence level, usually expressed as a percentage. Thus, in the world of statistics, one describes a confidence interval in terms of 2 standard deviations from the mean (i.e., 95% confidence), 3 standard deviations from the mean (99.7% confidence), etc. So, the truism saying began: "I Am 99.7% Confident That I Fall Within 3 Standard Deviations From The Mean".
No need to be a statistician to showcase your wry knowledge of statistics with a dose of confidence interval humor with any of these timeless gifts! For all those who know that they fall within 3 standard deviations from the mean!
