Authorised final reports are published electronically. Each report includes a collation of participants’ results (egg type identified and count), mean values of egg counts for each PT-sample calculated from participants’ results, comments and a link to a statistical analysis report.
The statistical analysis is supplementary. Z-scores are calculated from the participants’ results to identify questionable or outlier results by a robust statistical method. The mean value (consensus value) is used in determining these z-scores and as the Intended Result.
