| Abstract: | In order to evaluate the test ability of 16 examiners in three laboratories,items of total hardness of the ground water quality were selected to assess the proficiency,using robust statistics to analyze errors, for the item of total hardness of the ground water quality,there are two examiners with questionable results,ability comparison test is an effective way to find out existing problems in test and to improve testing proficiency. |
