Below is a Bland Altman Plot that examines the agreement between an our new Body Composition App (%Fat3C-IMAGE) and the Laboratory Criterion (%Fat4C-UWW). The average of the 2 measures is plotted on the X axis. The difference between the two measures is plotted on the Y axis.

Given the observed correlation between the X and Y axis show in red, would we anticipate that:

a. TheBody CompositionApp(%Fat3C-IMAGE)will overestimate for adults with higher %Fat

b. The Body CompositionApp(%Fat3C-IMAGE) willunderestimate for adults with higher %Fat

c. The Body CompositionApp(%Fat3C-IMAGE)measure with equal accuracy for all adults regardless of their %Fat
