Syntax

expression.Z_TEST(arg1, arg2, arg3);

expression - A variable that represents a ApiWorksheetFunction class.

Parameters

Name	Required/Optional	Data type	Default	Description
arg1	Required	number[]	ApiRange
arg2	Required	ApiRange	ApiName	number
arg3	Required	ApiRange	ApiName	number

Returns

number

Example

var oWorksheet = Api.GetActiveSheet();
var argumentsArr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16];

// Place the numbers in cells
for (var i = 0; i < argumentsArr.length; i++) {
    oWorksheet.GetRange("A" + (i + 1)).SetValue(argumentsArr[i]);
}

// Get values from the range
var data = oWorksheet.GetRange("A1:A16");

// Calculate the TRIMMEAN of the range A1:A16
var oFunction = Api.GetWorksheetFunction();
var result = oFunction.Z_TEST(data, 4);
oWorksheet.GetRange("B1").SetValue(result);
