在代码测试的次数方面，在之前的项目中我们没有打算在我们的软件中进行 100% 代码覆盖率的测试。

In terms of how much of the code to test, on previous projects we hadn.t aimed for 100% code coverage in our software.

对每次尝试来说，训练集都非常大，这意味着你的算法有足够的数据进行学习，而且这样一来也提供了足够多的测试次数(20次，而不是5次或10次)。

This gives you a much larger training set for each trial, meaning that your algorithm will have enough data to learn from, but it also gives a fairly large number of tests (20 instead of 5 or 10).

她说，为了证实打孩子造成智商下降的假说，最好的办法就是对一个孩子反复进行智商测试同时记录他挨打的次数。

'the best way to test their hypothesis that spanking lowers IQ would be to... to measure IQ in a child repeatedly over time while measuring the Numbers of spankings administered,' Friedman said.
