Dictionary · 1. Qualitative research methods: when to use them and how to judge them; 2. How to use and assess qualitative research methods

Qualitative measurement engages research methods and techniques to provide information about the nature of phenomenon. Qualitative methods are designed for systematic collection, organization, description and interpretation of non-numeric (textual, verbal or visual) data (Hammarberg et. al, 2016). Qualitative measurement generally answers questions about why, for whom, when, and how something is (or is not) observed, whereas quantitative measurement answers questions about what is observed. Elements assessed using qualitative measurement may include contextual norms or meaning, socio-cultural dynamics, individual or collective beliefs, and complex multi-component interactions or interventions (Busetto et. al, 2020).
