Bland-Altman Plot
A Bland-Altman plot is a statistical method used to assess the agreement between two measurement techniques or instruments, typically in medical or scientific research. It visualizes the differences between paired measurements against their averages, helping identify systematic bias, limits of agreement, and outliers. This graphical tool is essential for method comparison studies where assessing measurement consistency is critical.
Developers should learn about Bland-Altman plots when working in data science, bioinformatics, or healthcare analytics, especially for validating new measurement tools against established standards. It's used in scenarios like comparing diagnostic devices, evaluating algorithm performance in machine learning models for medical data, or ensuring data quality in clinical trials. Understanding this concept helps in interpreting and communicating reliability assessments in interdisciplinary projects.
