普查是最簡單的方法，也是最不用學習統計的量化研究。
而學習統計是為了「推論」，比方說有一萬人的國小老師，要「抽樣」100人來「推論」到10000人，統計就是在這時候來做「檢定」用。
統計可以幫助你不用去做到1萬人次的普查，可以節省金費和心力。
網路問卷是最難做分析的，因為無法得知母群體的來源與特性(是否常態分布等)，若用傳統的統計分析，則會出現爭議，若使用「無母數統計」會增加分析的難度。

KM LOG1: The Nonsense of Knowledge Management
Part I:
Data and information may be managed, and information resource may be managed, but knowledge can never be managed.
When employees leave a company, their knowledge goes with them, no matter how much they've shared.
Can "Tacit knowledge" be captured? The answer, of course, is that it cannot be "captured" - it can only be demonstrated through our expressible knowledge an through our acts.
The conclusion is reached that "knowledge management" is an umbrella term for a variety of organization. Those activities that are not concerned with the management of information are concerned with the management of work practice.
Part II
KM is a papular work in business work, but even in acdamic community, they still use 'knowledge' as a synonym for 'information'. A lot of KM activities are just a kind of Information Management.
Even though, it is not saying that people to contribute effectively the management of organizations is impossible and that sharing knowledge is impossible. It's just to differcult to do it.
Part IV
The opinion of this article made me shock. I have never heard opinions like this.
Before I read this report, I knew KM was a kind of work to make the knowledge of a company can be stored and shared. Especilly sharing, it was the most important activity of KM. But now, I agree that 'Tacit Knowledge' can't be captured, the knowledge will go with retired employees, no matter how much they shared before. I also argee that 'Information' and 'Knowledge' these two words make people confused.
In this condition, KM may be a fad. But I still believe KM should be developed. Because of the economy of knowledge, in this term, we never use ‘information’ to replace ‘knowledge’. It is a new word and this is a new world, the important element of companies (or others) is not only information but knowledge. So we do need a new discipline to deal with this new element.
I believe Wilson didn’t mean to offend the people who advocate managing knowledge. He just wanted to remind us the knowledge couldn’t be handled as like as we handled information before.
