Confidence Interval

This is part of the QCE Specialist Maths course. In this post, we will understand the concept of an interval estimate for a parameter associated with a random variable. The confidence interval (CI) is a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval.
