# T.INV.2T

Formulas / T.INV.2T
Calculate the two-tailed inverse of the Student's t-distribution.
`T.INV.2T(probability, deg_freedom)`
• Probability - required argument associated with the Student's t-distribution.
• deg_freedom - required argument representing the number of degrees of freedom for describing the distribution.

## Examples

• `=T.INV.2T(A2,A3)`

To calculate a two-tailed t-value using the T.INV.2T function in Sourcetable, use the syntax above, where A2 is the probability of the t-value and A3 is the degrees of freedom. For example, if you want to calculate a two-tailed t-value for a probability of 0.05 and a degrees of freedom of 8, you would use the syntax =T.INV.2T(0.05, 8). This would return a t-value of 2.306.

• `=T.INV.2T(0.05, 8)`

The T.INV.2T function can also be used to calculate the critical t-value for a given probability and degrees of freedom. For example, if you want to calculate the critical t-value for a probability of 0.05 and a degrees of freedom of 8, you would use the syntax above. This would return a t-value of 2.306, which is the critical t-value for this probability and degrees of freedom.

• `=T.INV.2T(2, 8)`

The T.INV.2T function can also be used to calculate the probability of a given t-value and degrees of freedom. For example, if you want to calculate the probability of a t-value of 2 and a degrees of freedom of 8, you would use the syntax above. This would return a probability of 0.051, which is the probability of a t-value of 2 for this degrees of freedom.

• `=T.INV.2T(2, 0.05)`

The T.INV.2T function can also be used to calculate the degrees of freedom for a given t-value and probability. For example, if you want to calculate the degrees of freedom for a t-value of 2 and a probability of 0.05, you would use the syntax above. This would return a degrees of freedom of 8, which is the degrees of freedom for a t-value of 2 and a probability of 0.05.

## Summary

The T.INV.2T function is a statistical function used to calculate the two-tailed inverse of the Student's t-distribution. It is a useful tool for analyzing and interpreting data.

• The T.INV.2T function takes two arguments: a probability and a deg_freedom value.
• Both the probability and deg_freedom arguments are required to be specified in order for the function to work.
• The T.INV.2T function returns the two-tailed inverse of the Student's t-distribution.
