aV = [ 2, 4, 4, 5, 7, 9, 12, 25 ] oS = StzTukeySummaryQ(aV) ? oS.Why() ? @@( oS.Fourths() ) ? oS.FourthSpread()
Output
a Tukey summary of 8 value(s) under Tukey's fourths (hinges at depth (floor((n+1)/2)+1)/2): hinges 4 | 6 | 10.5, fourth-spread 6.5, 1 outside, 0 far out [ 4, 10.50 ] 6.50

The extensions of this method
Each extension, and whether it exists for this method; an extension that exists combines with the others (FindSTCS).
Extension
Exists
What it adds · The names
Q
no
does what the method does, then returns the object, so the call can be chained
QQ
no
chains on the next, more specific type of object (the Q ladder)
QQQ
no
chains on the most specific type of object (the Q ladder)
QRT
no
returns the result as an object of the requested type
CS
no
takes a case-sensitivity flag
ST
no
takes the position to start from (StartingAt)
IB
no
takes bounds that are included (IncludingBounds)
XT
no
the extended form: more parameters than the base method
XTT
no
yet another extension: a further extended form, after XT
Z
no
includes the position in what it returns
ZZ
no
returns positions as sections, [start, end]
W
no
selects by a condition
WF
no
selects by a condition, with the expressive keywords (@NextItem, @PreviousItem...)
D
no
takes a direction, forward or backward (Directional)
F
no
takes a function (the condition or the update is given as a function); the forms document also uses F for the future form, which defers the action
Many
no
works on a collection of items instead of one (the plural form)
Except
no
takes exceptions, what to leave out (the exceptional form)
U
no
returns the result without duplication
Every example is a test file of the library, run inside the library for this page; only those whose output kept every promise their file wrote are shown.
