Aug 04, 2011 · Values with uncertainties failing the Pn test were omitted from the calculation of the adjusted statistics. The formula for the ‘Z’ test compares the bias in each participant’s value with their reported uncertainty. This test is not used for pass/fail of the proficiency test but does require possible corrective action.

For example, if a researcher knows that the statistics in the study follow a Z or standard normal distribution, there are two parameters that he/she needs to estimate, the population mean (μ) and the population variance (σ2). Most of the time, the researcher know one of the parameters and need to estimate the other.
