Bland and Altman plot for peak torque repeatability. Legend: Bland and Altman plot of the difference between test and retest peak torque values. The left panel illustrates that the homoscedasticity assumption would be violated if the 4 kg condition were included in the analysis (a correlation exists, p < 0.05). The right panel illustrates that the homoscedasticity assumption is met (no correlation exists, p > 0.05) if the 4 kg condition is dropped
