T.DIST.2T functionThe T.DIST.2T function returns the two tailed Student distribution for a value x. Along with T.DIST.RT, this function replaces TDIST and is equivalent to calling TDIST with the tails argument set to 2.
Parts of a T.DIST.2T function
Required. The x value to evaluate the distribution at.
Required. The degrees of freedom.
Example 1: T.DIST.2T(1.96, 60)
Example 2: T.DIST.2T(1, 2)
If deg_freedom is less than 1, returns an #NUM error.
If x is negative, returns an #NUM error.
Along with T.DIST.RT, this formula replaces the TDIST formula. This is equivalent to calling the TDIST formula with tails = 2.
Result for A1=T.DIST.2T(1.96, 60)
Result for A1=T.DIST.2T(1, 2)
T.DIST: The T.DIST function returns the right tailed Student distribution for a value x.
T.DIST.RT: Returns the right tailed Student distribution for a value x.
TDIST: Calculates the probability for Student’s t-distribution with a given input (x).
