Map and Table Calculation

VAR( ) function

Returns the variance of a value column.

Syntax

VAR(ValueColumn)

Input

Output

Notes:

• The variance is calculated according to the following formula:
• The VAR function can only be used on the command line of the table window; it cannot be used on the command line of the Main window.
• The VAR 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:

• The smaller the variance, 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.
