TInv() returns the t value of the student's t distribution as a function of the probability and the degrees of freedom.
Syntax:
TINV(prob, degrees_freedom)
Return data type: number
Arguments:
Argument | Description |
---|---|
prob | A two-tailed probability associated with the t-distribution. It must be a number between 0 and 1. |
degrees_freedom | An integer stating the number of degrees of freedom. |
Limitations:
All arguments must be numeric, else NULL will be returned.
This function is related to the TDist
function in the following way:
If prob = TDIST(value, df ,2),
then TINV(prob, df) = value.
