Methods for Data Collection

I have been thinking about different ways to collect my data and how to explain them in my essay.
My initial idea was to do:

• Quantitive online surveys
• Qualitative interviews 
• Observation ( my own ethnographic experiences)
• Narrative data (hearing peoples stories)

However after revisiting my cycle I remembered that on this course we are using the qualitative non-positivist approach, this made me re-think my data collection methods as I want to avoid pre-judging what causes certain behaviour, and that by using quantitive surveys with multiple choice questions I could put ideas in to peoples heads which would create inaccurate results.  I am still hoping to use online surveys (as they allow people to answer the questions anonymously) but to collect qualitative data.

I am really interested to hear other ideas and other ways to collect data.
