How is the analysis in these specific articles different? What are some examples of quantitative data analysis tests?

Quantitative: “Mean days of dressings were 17.2 (SD +3.55) for the NPWT (negative pressure wound therapy) as compared to 34.9 (SD +5.96) days in the conventional group (p< 0.001)” (Vaidhya, Panchal, & Anchalia, 2015, p. S526).
Qualitative: “Caregivers identified critical areas where they felt unprepared to assume the caregiving role after discharge from inpatient rehabilitation. Steps to improve preparation include (a) conducting a risk assessment of the patient and caregiver;(b) identifying and prioritizing gaps between the patient’s needs and caregiver’s commitment and capacity; and (c) developing a plan for improving caregiver readiness” (Lutz, et.al. 2017, p. 880).
