Questions tagged [confidence-interval]
In statistics, a confidence interval is a measure of the precision of an estimate of an underlying parameter. In principle, if the estimate is computed several times on independent samples of data, the parameter should fall within associated confidence intervals a set proportion of the time. This proportion is known as the coverage probability, and is most commonly set to be 95%.
