“Coefficient of Variation” (CV) is suitable for comparing the dispersion (Variation) of two groups of data collected with different measurement units. In this statistical index, the ratio of dispersion to a central criterion is measured. In fact, this index shows how much the standard deviation of the values changes per unit of change in the […]
Regression methods model the relationship between independent and dependent variables. Linear regression models are widely used; however, they may not be suitable when the relationship between variables isn’t linear. Polynomial regression is an alternative that models the relationship of the dependent variable as a polynomial function of the independent variable. This post (from Armancomputer blog) […]
Descriptive statistics indices, such as Central Tendency indices or dispersion measures, are used to identify the statistical population. But using each one alone may not have a good result. Simultaneous attention to the criteria of concentration and dispersion helps the statistical population to be better known and its behavior can be compared and analyzed. they […]
