scipy.stats.mstats.skew(a, axis=0, bias=True)

Computes the skewness of a data set.

For normally distributed data, the skewness should be about 0. A skewness value > 0 means that there is more weight in the left tail of the distribution. The function skewtest() can be used to determine if the skewness value is close enough to 0, statistically speaking.

bias : bool

If False, then the calculations are corrected for statistical bias.
