Data dispersivity
WebThe dispersivity values are mainly limited by the fact that none of these estimates are site-specific. In 1992 a data tabulation was published that related problem (plume) scale to dispersivity. The various "rules-of-thumb" are either based on this data set or can be related to it. Dispersivity Data (Gelhar et al.) WebIn excel you can use the following functions for finding the Quartile. =QUARTILE(data, quartile number) =QUARTILE(data,1), for Q1. =QUARTILE(data,2), for Q2. =QUARTILE(data,3), for Q3. After finding all the quartiles you can use the mathematical calculation for finding the fence and IQR. IQR and FENCE.
