| Abstract: | The t distribution is one of three most important distributions which are applied widely in mathematically statistical analysis, most of the teaching material not including or only use the direct method to derivate the probability density function of the distribution. In this paper, the transform method which features a more simple operation and less difficult computation is presented for derivation. |
