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.
我们以说我们的 Z 统量,对,我们以称之为我们的 Z 分数我们的 Z 统量, 我们偏离平均值的标准差数是 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.
突然间,这变得非常干净——我们只是说 2 pi 乘以我们的方差, 乘以 e 到我们远离均值的标准差数。
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差数,我们在最后几个视频中采样的男女之间的实际差异为 0. 051。
