SKE SKEW returns the skewness of a distribution.
Skewness refers to the asymmetr y of a distribution around its mean. Positive skewness
indicates a distribution with an asymmetric tail extending towards more positive values. Negative
skewness indicates a distribution with an asymmetric tail extending towards more negative
values. Figure 11.42 illustrates the SKEW function.
You can specify up to 30 arguments for the SKEW function. Arguments
can be cell references, arrays, or range names. Blank cells or cells that
contain a text, or logical values are ignored. Cells containing zero (0)
are included in the calculation.
