Normality measurement

WebNormality is an ambiguous measure of the concentration of a given reagent in solution. It needs a definition of the equivalence factor, which depends on the definition of the reaction unit (and therefore equivalents). The same solution can possess different normalities for different reactions. Web22 de nov. de 2024 · Just like Skewness, Kurtosis is a moment based measure and, it is a central, standardized moment. Because it is the fourth moment, Kurtosis is always positive. Kurtosis is sensitive to departures from normality on the tails. Because of the 4th power, smaller values of centralized values (y_i-µ) in the above equation are greatly de …
