DEFINITION of 'Confidence Interval'. A term used in inferential statistics that measures the probability that a population parameter will fall between two set values. The confidence interval can take any number of probabilities, with the most common being 95% or 99%. Next Up.
Associated with a confidence interval there is a confidence level or confidence coefficient. It is to be noted that the interval estimation and testing of hypothesis are two parallel developments in Statistics. It is easy to see the following result. Confidence level of a confidence interval = 1 - significance level of the associated test. i.e. Confidence level of a confidence interval = 1- Î±, where Î± is the significance level of the associated test. To make the concepts clear first, I will provide the procedure for finding a confidence interval and test construction:
