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 Z ,对,我们可以称之为我们 Z 分数或我们 Z , 我们偏离平均值标准差数是 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 Z 分数,即我们实际结果与平均值标准差数,我们在最后几个视频中采样男女之间实际差异为 0. 051。
