A percentenile is a numerical measure that is the reference point under which a certain percentage of the values of the target population is covered. Because of the conceptual simplicity and context-free function, percentiles are often used to determine the relative size and considerable importance of quantitative measures in all scientific fields. For example, children`s health conditions are often assessed based on their weight and height against national averages and perzentiles in growth charts. In addition, reference limit values are widely applied in medicine and related areas to identify an informative measurement range from a reference population. The most typical reference limits include the central 95% of values in the interested population. The 95% compliance limits of Bland and Altman [1, 2] are an important application of the 2.5. .
