"Qualitative research designs are focused on exploring, explaining, and developing deep understanding of specific phenomena. [...] Qualitative research allows the researcher to get a deeper understanding of a problem or phenomenon through interviews (structured and semistructured), analysis of images, and observations" (Marshall, 2020, Chapter 7).
"Qualitative research is explanatory, descriptive, and inductive in nature. It uses words, as opposed to numbers, to explain a phenomenon. Qualitative research lets us see the world through the eyes of another [...]. Qualitative researchers assume that we can only understand these things if we consider the context in which they take place, and this is why most qualitative research takes place in naturalistic settings. Qualitative studies make the world of an individual visible to the rest of us" (Toles & Barroso, 2018, Chapter 5).
