What is Skewness?

Skewness is a measure of asymmetry or distortion of symmetric distribution. It measures the deviation of the given distribution of a?random variable?from a symmetric distribution, such as normal distribution.?

A normal distribution is without any skewness, as it is symmetrical on both sides. Hence, a curve is regarded as skewed if it is shifted towards the right or the left.

什么是偏度？

偏度是對稱分布的不對稱性或失真的量度。它測量隨機變量的給定分布與對稱分布（例如正態(tài)分布）的偏差。

正態(tài)分布沒有任何偏度，因為它在兩側(cè)是對稱的。因此，如果曲線向右或向左移動，則認為曲線是有偏度的。
