請幫忙!!想知做quantitative同qualitative research method既好處同壞處

Quantitative Research - showing numerical data; asking what, where, when Questions
Adv: low cost, reaching large sample size
Disadv: provide less detail on behaviour, attitudes and motivation; result may get repeated which gives high reliabilty
Example: Survey, Questionaire

Qualitative Research - showing individual's behaviour, attitude; asking why , how Questions
Adv: more in-depth, can address problem with reliability
Disadv: expensive, time consuming
Example: Focus Group, Interview

It doesn't say which research method is easier to do, but depends on what kind of information you would like to get.

I found an essay on web about advantages and disadvantages of quantitative research and qualitative reserach: http://www.roboneill.co.uk/papers/research_methods.htm
