Or we could say that our Z-statistic, right, we could call this our Z-score or our Z-statistic, the number of standard deviations we are away from our mean is 2.14.
或者我们可以说我们的 Z ,对,我们可以称之为我们的 Z 分数或我们的 Z , 我们偏离平均值的标准数是 2. 14。
And all of a sudden, this becomes a very clean-- we just say 2 pi times our variance, times e to the number of standard deviations we are away from the mean.
Our Z-score, the number of standard deviations that our actual result is away from the mean, the actual difference that we sampled in the last few videos between the men and the women was 0.051.
我们的 Z 分数,即我们的实际结果与平均值的标准数,我们在最后几个视频中采样的男女之间的实际异为 0. 051。
