From the data table, click on the toolbar, and then choose Bland-Altman from the list of one-way analyses. Designate the columns with the data (usually A and B), and choose how to plot the data. You can plot the difference, the ratio, or the percent difference.

A Bland–Altman plot (difference plot) in analytical chemistry or biomedicine is a method of data plotting used in analyzing the agreement between two different assays.

In 1983 Altman and Bland re-proposed an alternative analysis, firstly presented by Eksborg in 1981 (1), based on the quantification of the agreement between two quantitative measurements by studying the mean difference and constructing limits of agreement (2).

To create a Bland-Altman plot (often referred to as the difference plot), you only need to select two metric variables. To create a Bland-Altman analysis, two dependent samples are needed.

In essence, a Bland-Altman plot is a scatter plot where the differences between two measurements are plotted against their averages. This helps to visualize the degree of agreement between the two raters and identify any systematic bias.

Bland-Altman plots are used to assess the agreement between two methods of measuring something, usually clinical information. They were discussed in Bland & Altman’s 1986 paper (available here and/or here) and see also the Wikipedia page. Here is the example data that was used in the 1986 paper in data frame format:

Bland and Altman devised a simple, but informative, way of graphing the comparison of two assay methods: First measure multiple samples using both methods. Then plot the...
