Which of the following examples shows data from a qualitative study? Select one: a. "Three main categories emerged from the analysis: the dependent body reflect changes in the women's bodily strength and performance, as they moved from being care providers into those who need care; this was associated with experience of a sense of paralysis, shame, and burden. " b. "Independent t test that the quantity of sleeping in the experimental group was significantly higher than control group (t=3.18, p<0.05) (Table 2). Therefore, hypothesis 1 was supported. c. "Among the 27 hospitals excluded from the analysis, 23 hospitals had less than 100 admissions in total, and four hospitals were excluded because of missing data" d. "As shown in Table 3, the total mean on the SET (Nurses' Self-Efficacy in Managing Children's Pain) was 26.28 (maximum score = 30), indicating that overall, the participants had a high level of self-efficacy in regard to pediatric pain management".
