Z-Score Summary - Concrete Proficiency Testing Program (80) Z-SCORES SUMMARY. Concrete June 2018 (80)

Transcription

1 Z-SCORES SUMMARY Concrete June 2018 (80) The proficiency program was conducted in June 2018 with participants throughout Australia. AS 1012 test methods were preferred but other methods were allowed in this program. This summary provides the z-scores for the following tests. Compressive Strength Mass per Unit Volume A z-score summary is provided to allow participants to gauge performance and address outliers as early as possible. It is recommended that any remedial action be undertaken cautiously until the final report for the program has been consulted. Participants will find that their code appears once in either sample (A1 and B1) or (A2 and B2). Participants may forward the summary report to NATA as an indication of a participant s general performance. The z-scores shown are unlikely to change significantly. Small changes however may become necessary during preparation of the final report. The final report provides other information, apart from z-scores, that may be used to access performance and interpret the significance of outliers. The final report once issued supersedes the z-score summary. All participants need to assess their overall performance once the final report has been issued.

The results column shows a blank entry or '' for those participants that did not submit a result for this test. Result shown with a "R" has been rejected as an erroneous result and is not part of the sample population. Results in green have been either calculated or amended by the program coordinator. Minimum, Maximum and Range are calculated with outliers excluded, those in brackets include outliers. Copyright: LabSmart Services Pty Ltd Issued - 5 August 2018 Page 2 of 9
