Qualitative analysis is important if you would like to step further in a quantitative analysis.
Carefully design the questions and the methods of collecting your data.
In some cases depending on the type of groups involved in your research you will also need to have an ethical clearance before starting any research practice.
Clearly state your research goals and try to avoid broad questions and discussions over the topic - in some cases the latter might be useful since they can provide extra information that you haven't thought before but they can also miss-lead your research.
As it was mentioned before - visualise your data in order to reveal patterns and information hidden behind - draw a diagram of relationships between the data collected and the initial research questions - then decide about the quantitative methods that will help you to explain better these relationships.
