This occurs in different statistical data sets, including frequency distributions. Any distribution with its left side shaped differently than its right side is a skewed distribution.
Webband the line shape has features of both Gaussian and Lorentzian character. The simplest model for this involves the combination Gaussian-Lorentzian (G-L) profile, repre-sented as A*G + (1-A)*L with A (a variable parameter in the fit) being the fraction of Gaussian character (0 ≤ A ≤ 1). A more complex combination of Gaussian and Lorentzian WebbSkewness can be shown with a list of numbers as well as on a graph. For example, take the numbers 1,2, and 3. They are evenly spaced, with 2 as the mean (1 + 2 + 3 / 3 = 6 / 3 = 2). If you add a number to the far left (think in terms of adding a value to the number line), the distribution becomes left skewed: -10, 1, 2, 3.
