The angles in the transverse plane (external rotation) of the hip, knee, and ankle joints were examined for each saute, observing their behavior through the mean values and angular range of motion as well as the coefficient of variability. The normality and homoscedasticity of the angles were confirmed using Shapiro Wilks and Levene tests, respectively.
At the height-retaining leg held forward at 90[degrees], the experimental group obtained an average of 13.2 [+ or -] 4.70 seconds on initial testing, with a coefficient of variability of 13.126%, indicating a mean average homogeneity, and an average of 22.7 [+ or -] 6.41 seconds at final testing with a coefficient of variation of 5,974%.
Then eight parametric stability parameters were performed inaccordance with Eberhart and Russel's (1966) the regression coefficient (bi) and deviation from regression (Eq.), Pinthus's (1973) coefficients of determination (R2), Wricks's (1962) ecovalance (Eq.), Shukla's (1972) stability variance (Eq.), Francis and Kannenberg's (1978) coefficient of variability (CVi) and genotypic variance (Eq.); Lin and Binn's (1988) superiority index (Pi) which the genotypes of greatest interest would be those with the lowest Pi values.
Within-subject BP measurement variability was calculated from the SD of the three repeated measurements and also expressed as a coefficient of variability (CV = 100 x SD/mean, %), respectively, for the BPs measured from the manual auscultatory and the two automatic oscillometric techniques and separately for both the normotensive and hypertensive groups.
Nevertheless, in a sample of adherent clozapine-treated patients, investigators found that 98% of patients had a coefficient of variability (CV) of 30% for sequential plasma concentrations (mean CV, 14%).

BGL: blood glucose level; CGM: continuous glucose monitoring; CONGA (1, 2, 4): continuous overall net glycemic action (at 1 hour, 2 hours, and 4 hours); CV: coefficient of variability; HbA1c: glycated haemoglobin; MAGE: mean amplitude glycemic excursions; NGAL: neutrophil associated gelatinase lipocalin; PCI: percutaneous coronary intervention; SD: standard deviation.
A greater phenotypic coefficient of variability (PCOV) was observed than genotypic coefficient of the variation (GCOV) for all the traits (Table 2) which indicated that the apparent variation is not only due to genotypes but also due to the influence of environment.
The results show that the coefficient of variability is the lowest for the CCC in innovation-based companies, which confirms the hypothesis.
Estimates of genetic parameters like phenotypic and genotypic coefficient of variability (PCV, GCV), heritability ([h.sup.2]) and genetic advance (GA) for various quantitative traits are useful in designing an effective breeding programme.
