Service FAQ

Q: What information should I provide when sending a request for quotation (RFQ)?
A: We suggest you provide the following information when sending an authorized request:
1. Respondent: Who are the qualified respondents? What are the screening questions? 2. Contents: What are you investigating in? We can provide a precise fee estimation if we are given questionnaires or drafts. 3. Sample size: What is your expected effective sample size? Please discuss with us if you only have scarce idea. We are more than happy to provide suggestion based on objectives. 4. Methodology: Phone interview, face-to-face interview, or online survey? We can offer suggestion that best suits your need. 5. Other references: Have you conducted investigations like this before? How was the responds of the previous investigations?
Q: Does higher effective sample size gives lower unit price?
A: Not necessarily.If the population parameter covers large amount of samples, the higher effective sample size does give lower unit price. However, if the population parameter only contains low amount of samples, this requires high retrieve rate, thus raises the difficulty of execution. Once the retrieve rate exceeds certain threshold, the unit price of effective samples will increase in accordance with growth of sample size.
Q: Which methodology of investigation gives the best result?
A: There is no one single investigation method outranks others, whether it is telephone interview, face-to-face interview, and online survey. The most appropriate way is determined by several elements such as respondents, contents, timeline, budgets, etc. There are research institutes that focus on internet surveys overstress the benefits of conducting investigations over internet. However, they do not make strong cases, nor do other rigorous institutes agree with such view. As a matter of fact, each methodology has unique benefits and limits. We can only suggest one method is more suitable for one specific project, and there is no single method excels others.
Q: How high should I set for sample size?
A: We have to take several elements into account. The elements include sampling errors, population size, budgets, and timeline. We suggest you consult with us for required sample size when formulating the investigation projects.
Q: Qualitative interviews need fewer amounts of samples, so the costs are cheaper?
A: Not necessarily.Qualitative research is more time-consuming and energy-consuming. Organizing the interview scripts and filtering useful information require experience. Hence, the cost of conducing qualitative research may not be cheaper than quantitative research.
