[F1Confidence intervals of the median at 95% U.K.
The confidence intervals at 95% (value of the error of the first kind equal to 0,05 or 5%) represent the interval within which the value of the median could vary if it were possible to repeat an experiment an infinite number of times. In practice, it indicates the interval of variability of the test in the operating conditions adopted starting from the assumption that it is possible to repeat it many times. As with the CVr% , the interval helps to assess the reliability of the test.
where C = 1,96 for the confidence interval at the 95% level.
An example of the calculation sheet is presented in Annex I to the standard IOC/T 20/Doc. No 15.]
