Tukey<U+2019>s fences is a technique used in box plots. The non-outlier
range is defined with [Q1-k(Q3-Q1), Q3+k(Q3-Q1)], where Q1 and Q3
are the lower and upper quartiles respectively, k - some non-negative
constant (popular choice is 1.5). A value is an outlier based
on Tukey<U+2019>s fences when its value does not lie in non-outlier range.
