Basic Statistics (Mathematica Tutorial)

Basic descriptive statistics operations. Given a list with n elements x_i, the mean Mean[list] is defined to be μ(x)OverscriptBox[x, _]∑x_i/n. The variance Variance[list] ...

Take (Built-in Mathematica Symbol)

Take[list, n] gives the first n elements of list. Take[list, -n] gives the last n elements of list. Take[list, {m, n}] gives elements m through n of list. Take[list, seq_1, ...

Select (Built-in Mathematica Symbol)

Select[list, crit] picks out all elements e_i of list for which crit[e_i] is True. Select[list, crit, n] picks out the first n elements for which crit[e_i] is True.

Contexts (Mathematica Tutorial)

It is always a good idea to give variables and functions names that are as explicit as possible. Sometimes, however, such names may get inconveniently long. In Mathematica, ...

LocationEquivalenceTest (Built-in Mathematica Symbol)

LocationEquivalenceTest[{data_1, data_2, ...}] tests whether the means or medians of the data_i are equal. LocationEquivalenceTest[{data_1, ...}, " property"] returns the ...

Type Ctrl+DynamicBox[If[$OperatingSystem === MacOSX, T, D], ImageSizeCache -> {9., {0., 8.}}] or choose Graphics > Drawing Tools. For more information on each tool, click the ...

Processing Textual Data (Mathematica Guide)

Mathematica has uniquely flexible capabilities for processing large volumes of textual data. Most often data represented as a string is converted to lists or other constructs ...

TTest (Built-in Mathematica Symbol)

TTest[data] tests whether the mean of data is zero. TTest[{data_1, data_2}] tests whether the means of data_1 and data_2 are equal.TTest[dspec, \[Mu]_0] tests the mean ...

Colors (Mathematica Guide)

Combining a new level of programmatic support for symbolic color with carefully chosen aesthetic color parametrizations, Mathematica allows a uniquely flexible and compelling ...

Low-Level Interface Control (Mathematica Guide)

The core of Mathematica's unique power for building interfaces is in its extremely flexible high-level symbolic paradigm. But Mathematica also allows you to build interfaces ...
