1. Collect Data: Obtain paired measurements from two different methods on the same subjects. 2. Calculate Differences: Compute the differences between the two methods for each pair of observations. 3. Calculate Averages: Compute the average of the two methods for each pair of observations. 4. Plot the Data: Create a scatter plot with the average values on the x-axis and the differences on the y-axis. 5. Add Limits of Agreement: Calculate the mean difference and the limits of agreement, typically set at ±1.96 times the standard deviation of the differences.
