Bland-Altman Analysis
Analyze any type of data with Sourcetable. Talk to Sourcetable's AI chatbot to tell it what analysis you want to run, and watch Sourcetable do the rest.
Introduction
Bland-Altman Analysis is a statistical method that quantifies the agreement between two quantitative measurements. First presented by Eksborg in 1981 and later proposed by Altman and Bland in 1983, this analysis calculates mean differences and standard deviations to construct limits of agreement between measurements.
Traditionally, analysts perform Bland-Altman Analysis in Excel through a multi-step process: creating data tables, calculating differences, determining confidence intervals, and generating plots. While effective, this manual approach requires Excel expertise and can be time-consuming.
An AI-powered alternative, Sourcetable lets you perform complex analyses through natural conversation with an AI chatbot. Simply upload your data and tell Sourcetable what you want to analyze - the AI will handle the rest, from data processing to visualization, making Bland-Altman Analysis accessible to users of all skill levels.

Benefits of Bland-Altman Analysis with Sourcetable
Understanding Bland-Altman Analysis
Bland-Altman Analysis quantifies agreement between two measurement methods by calculating limits of agreement using mean and standard deviation differences. This statistical method provides a simple way to evaluate bias and estimates an agreement interval where 95% of measurement differences fall.
Key Advantages of Bland-Altman Analysis
The analysis enables visual examination of measurement agreement and quantifies bias effectively. It calculates agreement ranges using the formula d ±1.96s, where d is the mean difference and s is the standard deviation. This method works with both unit and percentage differences, supporting transformed data when needed.

Frequently Asked Questions
What is Bland-Altman Analysis and when should I use it?
Bland-Altman Analysis, also known as B&A plot analysis, is a method for comparing two measurements of the same substance. It quantifies agreement between two quantitative measurements by plotting the differences between paired measurements against their means. This analysis is particularly useful in method-comparison studies, laboratory research, and when evaluating agreement between two methods of clinical measurement.
What are the key components of a Bland-Altman plot?
A Bland-Altman plot consists of the difference between two paired measurements on the Y-axis and the mean of the two measurements on the X-axis. It calculates the mean difference and constructs limits of agreement, where 95% of the data points should lie within 2 standard deviations of the mean difference. The plot helps evaluate bias in mean differences and estimates an agreement interval.
How can I perform a Bland-Altman Analysis in Sourcetable?
