But what did that article he gave us last week say about the quality of data from questionnaires?
但上周给我们的那篇文章说了关于问卷中数据质量什么？
I'm pretty sure it recommended questionnaires as a source of highly reliable data.
我非常确定，推荐的问卷是有效数据的来源。
As long as you design the questionnaire properly in the first place, the data will be fine.
只要一开始就设计出正确的问卷，数据不会有问题的。
No, I'm sure it talked about drawbacks as well，didn't it?
不，我确定它还谈论了一些缺陷，不是吗？
Something about the response rate and the problems you get if ifs too low.
一些关于回应率低的问题。
Yeah, but we only need data from five subjects anyway.
是的，但总之，我们只有5个主题需要数据。
I suppose so. Another drawback I remember it mentioned was that questionnaire data tends not to reveal anything unexpected,
哦，似乎是这样。我记得它提到的另外一个缺陷在于，调查问卷不太可能揭示出乎意料的东西，
because it is limited to the questions fixed in advance by the researcher.
因为问卷仅限于研究者事先确定好的问题。
Come on，Rosa. This is only a practice. It's not meant to be real research, is it? Well, not sure about that.
拜托，Rose，这只是个练习而已。它原本就不是真正的研究，不是吗？嗯，我不是很确定。
