"Dip sampling" is a technique we use in a number of areas of policing where
we need to check that processes are being following properly without having
to look at every single case. We literally "dip" into the records at random
and check that the case we pick out has been processed properly, and - if
it hasn't - we can question the officers responsible.
这里的dip sampling要翻译成什么呢？用这种抽样方式得到的“dip samples”又译成
什么？谢谢。
