And that was a very good approximation to a sphere.

这种组合十分接近球形。

These are both pretty good approximations of normal distributions.

这些都是正态分布的很好的近似值。

So it might be pretty good approximation.

所以它可能是非常好的近似值。

And that probably would be a pretty good approximation for the variance of this entire population.

这可能是整个人口方差的一个很好的近似值。

But in general, a normal distribution is going to be a pretty good approximation for part A of this problem.

但总的来说，正态分布将是这个问题 A 部分的一个很好的近似值。

They then used thousands of images from the Internet to get the best approximation of what the subject was seeing based on brain scans.

然后，他们会基于脑扫描，用数千张从互联网中获得的图片，来推断出一个最接近的梦境。

Once again the whole point of this is to see that the normal distribution is a good approximation.

再一次，这一切的重点是看到正态分布是一个很好的近似值。

Scientists’ understanding of gravity has evolved since then, but Newton’s Law of Universal Gravitation is still a good approximation in most situations.

从那时起，科学家们对引力的理解发生了变化，但牛顿万有引力定律在大多数情况下仍然是一个很好的近似。

Now we need to find our best approximation for the Chinese porcelain dish from the Wanli period on the lower right of the painting.

现在我们需要找到画作右下角万历时期中国瓷盘的最佳近似值。

So it's not going to have infinitely long tails but, at least for the middle part of it, a normal distribution might be good approximation.

所以它不会有无限长的尾巴，但至少对于它的中间部分， 正态分布可能是很好的近似值。

Often they would be far too cumbersome, so we actually use a whole suite of other theories that are perfectly good approximations for those specific situations.

通常它们会太过麻烦，所以我们实际上使用了整套其他理论， 这些理论对于那些特定情况来说是完美的近似。

And that agreement means that our best approximation of how the building blocks of the universe interact with each other—the Standard Model—is probably safe for now.

该协议意味着我们对宇宙构建模块如何相互作用的最佳近似——标准模型——目前可能是安全的。

By the end of this video you should at least feel comfortable that this is a good approximation for the binomial distribution if you're taking enough trials.

到本视频结束时，如果您进行了足够多的试验，您至少应该感到舒服，因为这是二项分布的一个很好的近似值。

And if one body in a group of three is so light it exerts no significant force on the other two, the system behaves, with very good approximation, as a two-body system.

如果一组三个物体中的一个物体非常轻， 它不会对另外两个物体施加显着的力，那么系统的行为非常接近于一个双体系统。

Students who are more motivated do better in language acquisition, of those of you who study this, know that it's a little more complicated than this, but this is a good approximation.

那些更积极的学生在语言习得方面做得更好 你们研究这个的同学 知道这比这个要复杂一些 但这是一个很好的近似。

And that's frankly why the normal distribution shows up so much in statistics and why, frankly, it's a very good approximation for the sum or the means of a lot of processes.

坦率地说，这就是为什么正态分布在统计数据中出现如此多的原因，以及为什么坦率地说，它是许多过程的总和或均值的非常好的近似值。

That's not to say that they're entirely untranslatable, because we can do our best approximation of them, but there's that intuition that a non-native speaker wouldn't have that, je ne sais quoi, if you will.

这并不是说它们完全不可译，因为我们可以对它们进行最好的近似，但有一种直觉， 非母语人士不会有这种感觉，je ne sais quoi， 如果你愿意的话。

Initially the whole exercise -- I know I jump around a little bit -- is to show you that the normal distribution is a good approximation for the binomial distribution and vice versa.

最初整个练习——我知道我跳了一点——是为了告诉你正态分布是二项分布的一个很好的近似，反之亦然。
