Robust measures of scale
In
statistics
, a
robust measure of scale
is a
robust statistic
that quantifies the
statistical dispersion
in a set of
numerical
data
. The most common such statistics are the
interquartile range
(IQR) and the
median absolute deviation
(MAD). These are contrasted with conventional measures of scale, such as sample
variance
or sample
standard deviation
, which are non-robust, meaning greatly influenced by
outliers
.
