There are some situations when the process mean fluctuates from time to but is still considered as in-control and standard deviation a linear function of mean. In addition, in cases, variance actually dependent on each other. these situations, many researchers have suggested monitor CV (Coefficient Variation) single statistic. this paper, rigorous content analysis method (based 71 related studi...

In this paper, the neutrosophic trimmed average, standard deviation, and coefficient of variation (NTCV) are introduced. The application proposed descriptive statistics is given with help measurement data. comparisons NTCV compared existing (NCV). From comparisons, it concluded that more efficient than NCV in terms consistency measures indeterminacy. Based on study, recommended to apply industr...

1. Intra-arterial blood pressure and heart rate were recorded for 24 h in ambulant hospitalized patients of variable age who had normal blood pressure or essential hypertension. Mean 24 h values, standard deviations and variation coefficient were obtained as the averages of values separately analysed for 48 consecutive half-hour periods. 2. In older subjects standard deviation and variation coe...

The aim of this study was to investigate intra- and interspecimen repeatability of an experimental procedure, which determines elastic and viscoelastic properties of knee ligaments. The collateral ligaments from sheep were used and the repeatability was evaluated in terms of the coefficient of variation. The results indicated a good intraspecimen repeatability (the coefficient of variation gene...
