Here are my thoughts on your questions:
1. While quantitative research provides measurable data, qualitative research provides important contextual insights. The best approach uses both to gain a well-rounded understanding.
2. It's been over a year since I participated in a survey.
3. I tried to provide honest and thoughtful answers. However, as an individual data point, my responses alone may not have been that helpful without broader trends.
4. The research could have been improved by using open-ended questions to allow for nuanced responses, in addition to scaled questions. Focus groups or interviews may have elicited richer perspectives than just a survey. Both qualitative and quantitative methods combined can yield the most informative marketing research.
