Returns the test for independence: the value from the chi-squared distribution for the statistic and the appropriate degrees of freedom.

Syntax

expression.CHITEST(arg1, arg2);

expression - A variable that represents a ApiWorksheetFunction class.

Parameters

Name	Required/Optional	Data type	Default	Description
arg1	Required	ApiRange | ApiName | number | string | boolean		The range of data that contains observations to test against expected values.
arg2	Required	ApiRange | ApiName | number | string | boolean		The range of data that contains the ratio of the product of row totals and column totals to the grand total.

Returns

number
