Frequency Report No.: 1 Data Statistics Number of results 27 Number of excluded 0 results* Assigned value 29.73 Uncertainty of assigned 1.12 value SDPA** 4.64 * The influence of outliers on summary statistics has been minimized by the use of robust statistical methods but obvious blunders, such as those with incorrect units, decimal point errors, and results for a different proficiency test item are removed from the data set and treated separately. These results are not the subject to outlier tests or robust statistical methods. ** Method 1 in clause 6-3 (robust standard deviation) has been used for determination of SDPA. 14 Histogram of participants Z-scores for Mg 12 10 8 6 4 2 0 -3 -2 -1 0 1 2 3 More Z-scores Page 18 of 57
