This paper demonstrates that a single-sample t-score of |1| or -1 occurs when all vector observations equal mu except for one oddball, regardless of the oddball's value or the number of observations.

Abstract

If all observations in a vector $x$ are equal to mu except for one (the oddball), the one sample $t$ score will be |1|. If the oddball is mu, t = -1 and if the oddball is mu. t = 1, irrespective of the value of the oddball d, and irrespective of the number of observations.
