下表は，$Q(t)=\displaystyle \int_t^{\infty}p(t){\rm d}t=\frac{1}{\sqrt{2 \pi}}\int_t^{\infty}e^{-\frac{t^2}{2}}{\rm d}t$を与える $t$ の値を示したものであり，$Q(t)$は上図でハッチをした部分の面積を表している．
たとえば，$Q(t)=0.025$となるときの $t$ の値を求めたいときは，表の一番左の背景色が薄黄色の列で数値が$0.02$の行と，一番上の背景色が薄橙色の行で数値が$+0.005$の列との交わるセルの数字を読んで，$t=1.959963$，すなわち$Q(1.959963)=0.025$となる．
