But what did that article he gave us last week say about the quality of data from questionnaires?
但上周給我們的那篇文章說了關于問卷中數據質量什么?
I'm pretty sure it recommended questionnaires as a source of highly reliable data.
我非常確定,推薦的問卷是有效數據的來源。
As long as you design the questionnaire properly in the first place, the data will be fine.
只要一開始就設計出正確的問卷,數據不會有問題的。
No, I'm sure it talked about drawbacks as well,didn't it?
不,我確定它還談論了一些缺陷,不是嗎?
Something about the response rate and the problems you get if ifs too low.
一些關于回應率低的問題。
Yeah, but we only need data from five subjects anyway.
是的,但總之,我們只有5個主題需要數據。
I suppose so. Another drawback I remember it mentioned was that questionnaire data tends not to reveal anything unexpected,
哦,似乎是這樣。我記得它提到的另外一個缺陷在于,調查問卷不太可能揭示出乎意料的東西,
because it is limited to the questions fixed in advance by the researcher.
因為問卷僅限于研究者事先確定好的問題。
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,這只是個練習而已。它原本就不是真正的研究,不是嗎?嗯,我不是很確定。
