计数型MSA问题

大家帮忙检查一下，对以下的计数型MSA有什么建议：




ATTRIBUTE 的属性一致性分析

检验员自身

评估一致性

# 检 # 相
检验员 验数 符数 百分比 95 % 置信区间
LJF 30 30 100.00 (90.50, 100.00)
QZC 30 30 100.00 (90.50, 100.00)

# 相符数: 检验员在多个试验之间，他/她自身标准一致。


Fleiss Kappa 统计量

检验员 响应 Kappa Kappa 标准误 Z P(与 > 0 )
LJF N 1 0.105409 9.48683 0.0000
Y 1 0.105409 9.48683 0.0000
QZC N 1 0.105409 9.48683 0.0000
Y 1 0.105409 9.48683 0.0000

Test plan:

1. Prepare 30 pieces of samples (GBC12s), 15 pieces of them are good parts and the other 15 pieces of parts are drilled a 1mm holes on copper tube to make it leak;
2. Marked numbers on samples;
3. A operator and I made pressure test to the samples and recorded test results. The test is done by each person for 3 times.
4. Input test results to Minitab for Attribut Agreement Analysis
5. If the kappa value is greater than 0.9, the MSA of the station will reach our requirement.
6. The kappa value is 1 after calculated, so it means MSA of the station is ok.
