When to do quantitative and qualitative research?

Qualitative research is always the starting point when looking to identify new problems or opportunities. You can then use this as a basis to conduct more in-depth research later. Quantitative data help you to find the measurements that can be used to confirm and understand the individual problems or opportunities.

When do qualitative research?

The goal of qualitative research is to develop new theories or hypotheses on a topic. To do this, you concentrate on a few individual cases. The evaluation is done interpretatively. Quantitative research, on the other hand, aims to test existing theories or hypotheses.
