To select the appropriate Methods Of Collecting Data, you must take into account not only your research questions and the kind of data you want (numerical or descriptive), but also the availability of the participants (and your resources) in terms of time, budget, technology. I say, take a quantitative survey as an example of the type of survey to use in case you need statistical analysis; take interviews as the example of the type of survey to use in case you need in-depth perspectives. The more appropriate the method to your purpose, the more useful and relevant the information obtained by you.
