Parts 1 Through 3 Recap
In Part 1 (July 2021), when I started this series on test method comparison, I provided an overview of several basic precision concepts:
Accuracy
Bias
Correlation coefficient
Regression curve
Repeatability
Reproducibility
In Part 2 (August 2021) I explained why it is unrealistic to expect correlation coefficients between two methods, each based on a different parameter (e.g., CFU mL-1 and gene…
