Tukey’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’s fences when its value does not lie in non-outlier range.
