Bowley coefficient of skewness
WebSkewness. Lack of symmetry is called skewness. If a distribution is not symmetrical then it is called a skewed distribution. So, the mean, median and mode are different in value and one tail becomes longer than the other. The skewness may be positive or negative. If the frequency curve has a longer tail to right, the distribution is known as a ...
