Table 2.

Differences, associations and heteroscedasticity of the errors between the actual and predicted one-repetition maximums (1RM) during the squat exercise.

MVT	Method	Predicted 1RM (kg)	Raw Diff (kg)	ES	r(Pearson)	r(heteroscedasticity)
Group	Multiple-point	88.6 ± 17.6	3.1 ± 9.1	0.19	0.86	0.37
	Two-point	90.3 ± 17.8	4.7 ± 11.7	0.29	0.76	0.28
Individualised	Multiple-point	88.3 ± 19.5	2.7 ± 7.1	0.16	0.95	0.69
	Two-point	89.4 ± 18.1	3.8 ± 7.2	0.23	0.93	0.49

Data are mean ± standard deviation. Raw diff, Raw differences; ES, Cohen’s d effect size ([Predicted 1RM − Actual 1RM]/SD both); r_Peason, Pearson’s correlation coefficient; r_{heteroscedasticity}, heteroscedasticity of the errors.
