Map and Table Calculation

STD( ) or STDEV function

Returns the standard deviation of a value column.

Syntax

STD(ValueColumn)
STDEV(ValueColumn)

Input

Output

Notes:

• The STD and STDEV function are aliases of each other.
• The standard deviation is calculated according to the following formula:
• The STD and STDEV function can only be used on the command line of a table window; they cannot be used on the command line of the Main window.
• The STD and STDEV function can also be performed through a dialog box, see Column Statistics.
• When the input value is undefined, the record will be excluded from the calculation.

Tips:

• To calculate weighted standard deviations or standard deviations per class, see the AGGSTD function.
• The smaller the standard deviation, the less the values vary from the average.
• When the definition symbol = is used, a dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output column has been calculated.

Usable in

TabCalc, TabCalc pocket line calculator

Examples

TabCalc example:

OutCol = STD(InCol)
