一致性百分比和皮尔逊相关系数经常被用来代表检查者之间的可靠性，但这些措施可能会产生误导。不鼓励使用一致性百分比来衡量检查者之间的一致性，因为它没有考虑到仅仅由于偶然性而产生的一致性。在解释皮尔逊相关性时必须谨慎，因为它不受任何系统性偏倚的影响。可靠性研究的数据分析表明，尽管三名检查员的一致率和Kappa值一直很高，但Pearson相关性测量的可靠性并不一致。这项研究表明，相关性和kappa可以一起使用，以揭示非随机考官的错误。
Percent agreement and Pearson''s correlation coefficient are frequently used to represent inter-examiner reliability, but these measures can be misleading. The use of percent agreement to measure inter-examiner agreement should be discouraged, because it does not take into account the agreement due solely to chance. Caution must be used in the interpretation of Pearson''s correlation, because it is unaffected by the presence of any systematic biases. Analyses of data from a reliability study show that even though percent agreement and kappa were consistently high among three examiners, the reliability measured by Pearson''s correlation was inconsistent. This study shows that correlation and kappa can be used together to uncover nonrandom examiner error.
