About blind spots and Archimedes´ points

Knowing the blind spots of your own research is advisable, especially when conducting research continuously. What difference is there in conducting customer- satisfaction surveys face to face or by telephone? What would change if the data were collected by a cost-effective online panel? Are the results of the various survey forms valid? Our methodological experiments point out the quality of your data, the information that might get lost, and what you can confidently omit.
