T. INV.2T - the Function Returns the Two-sided Inverse of the Student's

This guide provides a practical overview of T. INV.2T - the Function Returns the Two-sided Inverse of the Student's, including its main features, benefits, limitations, and important considerations.

Description: The function returns the two-sided inverse of the Student's t-distribution. Support functions from Excel 2010 onwards.

Syntax: T. INV (probability, deg_freedom)

Inside:

- probability: Probability associated with t value of Student's t-distribution, which is a required parameter.

- deg_freedom: Number of degrees of freedom of the distribution, is a required parameter.

Attention:

- Any argument that is not a number -> the function returns the #VALUE! Error value

- If probability ? 0 or probability> 1 -> the function returns the #NUM! Error value

- If deg_freedom <1 -> the function returns the #NUM! Error value

- The minimum value of deg_freedom must be equal to 1.

- If deg_freedom is not an integer -> it is truncated to an integer.

- T. INV.2T returns the value of t , such that P (| X |> t) = probability with X being a random variable depending on the distribution and P (| X |> t) = P (X < -t or X> t).

For example:

Calculate the two-tailed inverse value of the Student 's t-distribution of values in the following data table:

- In the cell to calculate, enter the formula : = T. INV.2T (D6, D7)

- Press Enter -> the two-tailed inverse value of the Student 's t-distribution is:

- If the number of degrees of freedom is less than 1 -> the function returns the #NUM! Error value

- Where the probability of combining with the t value is greater than 1 -> the function returns the #NUM! Error value

Above are instructions and some specific examples when using T. INV.2T in Excel.

Good luck!
