Webb24 aug. 2024 · We favor parametric tests when measurements exhibit a sufficiently normal distribution. Skewness quantifies a distribution’s lack of symmetry with respect to the mean. Kurtosis quantifies the distribution’s “tailedness” and conveys the corresponding phenomenon’s tendency to produce values that are far from the mean. Normal … WebbSkewness The frequency of occurrence of large returns in a particular direction is measured by skewness.
