# T.INV.2T

## Understanding the T.INV.2t Function

The T.INV.2t function is used to calculate the inverse of the two-tailed Student’s t-distribution. This function is often used in statistical analysis to determine the confidence interval for a given set of data. The T.INV.2t function requires two arguments: probability and degrees of freedom.

The probability argument is the probability associated with the Student’s t-distribution. The degrees of freedom argument is the number of degrees of freedom in the distribution.

## Syntax of the T.INV.2t Function

The syntax of the T.INV.2t function is as follows:

T.INV.2t(probability, degrees_freedom)

``` Here, probability is the probability associated with the Student's t-distribution, and degrees_freedom is the number of degrees of freedom in the distribution. Using the T.INV.2t Function in Power BI To use the T.INV.2t function in Power BI, you need to follow these steps: 1. Open Power BI and create a new report. 2. Import the data you want to analyze into Power BI. 3. Click on the "New Measure" button in the "Modeling" tab. 4. Enter a name for the new measure and click on the formula bar. 5. Type the T.INV.2t function syntax into the formula bar, replacing the probability and degrees_freedom arguments with the appropriate values for your data. 6. Press "Enter" to calculate the result. Examples of Using the T.INV.2t Function in Power BI Let's look at some examples of using the T.INV.2t function in Power BI. Example 1 Suppose you have a dataset with 20 degrees of freedom and a probability of 0.05. To calculate the inverse of the two-tailed Student's t-distribution for this dataset, you would use the following syntax: ```

T.INV.2t(0.05, 20)

``` The result of this calculation would be -2.086015. Example 2 Suppose you have a dataset with 30 degrees of freedom and a probability of 0.01. To calculate the inverse of the two-tailed Student's t-distribution for this dataset, you would use the following syntax: ```

T.INV.2t(0.01, 30)

``` The result of this calculation would be -2.750013. The T.INV.2t function is a powerful tool for statistical analysis in Power BI. By using this function, you can calculate the inverse of the two-tailed Student's t-distribution to determine the confidence interval for your data. With the examples provided in this article, you should be able to use the T.INV.2t function in your own Power BI reports.
