How do you choose between qualitative and quantitative methodology for your research?

I am stuck deciding between interviews and a survey for my Masters dissertation on international student wellbeing at UK universities.nnThe core questions I am weighing up:n

• Do I want to understand why (qualitative) or how many/how much (quantitative)?
• Do I have access to enough participants for statistical significance?
• What does the existing literature in my area tend to use?

nnHas anyone navigated this decision?n

• What made you choose your methodology?
• Would you choose differently with hindsight?
• What surprised you about the analysis stage?
