Why confidence intervals are vital in analyzing mobile network experience

Things we have greater confidence in are things that we can state to a higher degree of precision, but no matter how well we measure something it will never get to the point where it can be stated as an absolute number. Scientists represent this level of precision with what is known as “confidence intervals”, a standard that has been adopted in all industries and domains across the globe.
