In statistics the term reliability is synonymous to reproducibility, like validity to accuracy, and precision to robustness (small-errors). For testing the reproducibility of quantitative diagnostic tests incorrect methods are often applied, like small mean differences between the first and second assessment, or a strong linear correlation between the first and second test but no direction coefficient of 45°. Correct methods include duplicate standard deviations, repeatability coefficients, and large intraclass correlations. In this chapter the incraclass correlation procedure is explained.
