Robust statistical analysis is used to convert the participants' results to a z-score which can identify questionable or outlier results by a robust statistical procedure.
The statistical analysis is based on calculating the median value which is not influenced by extreme results.
Statistical analysis is only performed when there are five or more participants’ results returned after the deadline has closed.
Authorised reports are published electronically. The report will show the intended results, as well as the results from all other participants. Histograms are accessible via a link on the authorised report.
