Table 2 Three-level model variance partition of standards and high/low controls across laboratories and plates

From: Measurement of cortisol in saliva: a comparison of measurement error within and between international academic-research laboratories

  9 laboratories (standards + 2 controls)
Variance across plates for the same samples within laboratories 0.001 0.11%
Variance across laboratories for the same samples 0.001 0.11%
Variance across samples 0.894 99.78%
Total variance 0.896
