> In this case, I think the article uses quantitative methods by conducting surveys that collect measurable data from a large number of participants. This data gives statistical information about user behaviors and preferences. At the same time, qualitative methods are used through in-depth interviews, which let researchers look closely at individual experiences and gather detailed information. By combining these two approaches, the study takes advantage of both: the wide-ranging and general insights from quantitative data and the rich, detailed context from qualitative data. I believe this mixed-method approach helps create a better understanding of how users engage with social media on their smartphones
