QuartileDeviation

QuartileDeviation[list]
gives the quartile deviation or semi-interquartile range of the elements in list.
QuartileDeviation[dist]
gives the quartile deviation or semi-interquartile range of the symbolic distribution dist.

QuartileDeviation works with any real numeric quantities:
Quartile deviations for columns of a matrix:
Obtain results at any precision:
Compute results for a large vector or matrix:
Obtain a robust estimate of dispersion when extreme values are present:
Measures based on the Mean are heavily influenced by extreme values:
QuartileDeviation is half the difference of linearly interpolated Quantile values:
QuartileDeviation is half the difference between the first and third quartiles:
QuartileDeviation requires numeric values:
