- asymmetry in a frequency distribution.
- a measure of such asymmetry.
- the quality or condition of being skew
- a measure of the symmetry of a distribution around its mean, esp the statistic B 1 = m 3 / (m 2) 3/2, where m 2 and m 3 are respectively the second and third moments of the distribution around the mean. In a normal distribution, B 1 = 0
