Research Methods Fundamentals
This sub-cluster is the entry point for research methods as a field: the vocabulary and orientation that the more specific sub-clusters above build on. It covers what distinguishes a research question from a hypothesis, how methodology (the overall approach) differs from method (a specific technique), and how the choice of approach connects back to a study's research paradigm. Readers arriving here are typically looking for orientation rather than a specific technique — more detailed treatment of any given method is found in the corresponding specific sub-cluster.
