T_INV_2T
Returns the two-tailed inverse of the Student's t-distribution.
Syntax
expression.T_INV_2T(arg1, arg2);
expression - A variable that represents a ApiWorksheetFunction class.
Parameters
| Name | Required/Optional | Data type | Default | Description |
|---|---|---|---|---|
| arg1 | Required | ApiRange | ApiName | number | The probability associated with the two-tailed Student's t-distribution, a number between 0 and 1 inclusive. | |
| arg2 | Required | ApiRange | ApiName | number | A positive integer indicating the number of degrees of freedom to characterize the distribution. |
Returns
number
Example
Find the t-value for a given two-tail probability in a spreadsheet.
// How do I find the critical t-value for a two-tailed test in a spreadsheet?
// Get the inverse of the two-tailed t-distribution for hypothesis testing in a spreadsheet.
let worksheet = Api.GetActiveSheet();
let func = Api.WorksheetFunction;
worksheet.GetRange("A1").SetValue(func.T_INV_2T(0.5, 10));
