Asymmetric Measurements

Asymmetric Measurements

1. What is it

   • They are indicators that allow establishing the degree of symmetry that a probability distribution of a random variable presents without having to make its graphic representation.

2. Type of measures

   • The distribution of the data can be concentrated on the left, right or uniform.

3. Pearson skewness coefficient

   • It can only be used on uniform, unimodal, and moderately skewed distributions.

4. Bowley–Yule asymmetry coefficient

   • It is based on the position of the quartiles and the median

5. Fisher's skewness coefficient

   • It is defined as the third moment about the mean and is the standard deviation, if the distribution is positively skewed or to the right; if the distribution is negative or left skewed.
