Scale of skewness
Webare scale-score-based, that is, using scores developed using a particular scaling method. In all of the cases presented here, this scaling method is Item Response Theory (IRT; see Lord, 1980). In the second part, we present the primary results of the paper in terms of skewness and kurtosis of both raw score and scale score distributions. WebThe skewness values of SS and ALK were between −0.5 and 0.5, and the distributions of two components were approximately symmetrical. Meanwhile, the skewness values of the other pollutants were less or more than −1 or 1, respectively, indicating highly …

WebThe maximum (theoretical) skewness is obtained by setting δ=1{\displaystyle {\delta =1}}in the skewness equation, giving γ1≈0.9952717{\displaystyle \gamma _{1}\approx 0.9952717}. However it is possible that the sample skewness is larger, and then α{\displaystyle \alpha }cannot be determined from these equations.
