Measures of Skewness
? The statistical technique to indicate the
direction and extent of skewness in the
distribution of numerical values in the data
set.
? A frequency distribution of the set of values
that is not Symmetrical(normal) is called
asymmetrical or skewed.

Skewed distributions
There are three types:
? Symmetrical distribution
A.M = Median = Mode
? Positively skewed distribution
A.M > Median > Mode
? Negatively skewed distribution.
A.M < Median < Mode
