Nov 15, 2012 at 23:56 comment added archie @Anderson. I see. So it really depends on the design of my experiment, my research questions, etc. I guess I have to carefully design my experiment to get the minimum and "optimum" sample size to avoid unnecessary costs. Thanks very much Anderson.

Nov 15, 2012 at 20:37 comment added user16892 This is a difficult question to answer, given the information provided above. Without knowing the number of attributes (and levels) in your experimental design and the number of questions you plan to ask of each respondent, I cannot provide a justifiable answer. Do keep in mind that the quality of your experimental design can greatly affect the variance of your parameter estimates and, therefore, increasing the efficiency of your design is equivalent to increasing your sample size.
