### Skewness

In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive or negative, or even undefined. The qualitative interpretation of the skew is complicated. For a unimodal distribution, negative skew indicates that the tai...

### skewness

An attribute of a distribution. A distribution that is symmetric around its mean has skewness zero, and is 'not skewed'. Skewness is calculated as E[(x-mu)3]/s3 where mu is the mean and s is the standard deviation. Source: Hogg and Craig, p 57 Contexts: statistics

### Skewness

Negative skewness means there is a substantial probability of a big negative return. Positive skewness means that there is a greater-than-normal probability of a big positive return.

### Skewness

Occurs when a distribution is not symmetrical about its mean. A distribution is symmetrical when its median, mean, and mode are equal. A positively skewed distribution occurs when the mean exceeds the median. A negatively skewed distribution occurs when the mean is less than the median. These conditions are also known as skewed to the right and ske...

Skewness defines the degree of asymmetry of the distribution around its central value.Skewness is defined aswheres = standard deviation of xN = total number of values of xSkewness is a unitless parameter known as the third order moment of a distribution.

### Skewness

Skewness is defined as asymmetry in the distribution of the sample data values. Values on one side of the distribution tend to be further from the 'middle' than values on the other side.
