I want this study to be high quality and taken very seriously by my colleagues, and so I think that the results should be as generalisable as possible within an Australian University context. What steps should I take?

a. It's not necessarily appropriate to aim for generalisability in a study like this. So I need to reconsider what my research aims are, and think about whether qualitative research is the best approach for me to use.
b. Recruit a very wide range of University students
c. Look at the sample sizes used in other relevant studies, and aim for a similar or larger sample size in my own study
d. Recruit as many participants as possible, but don't worry about which University they come from or what they are studying choose one correct answer
