Bland-Altman Plots for the 3-aspect BI test-retest reliability

In Figs 1-3 the differences of scores are plotted against mean scores of the 2 sessions(1). The limits of agreements (LOAs) of the 3 aspects ranged from -3.7 to 2.9 for actual performance, -7.5 to 5.0 for self-perceived difficulty, and -2.3 to 1.7 for ability.
