In which of the following research strategies is the principal orientation to…

Concept

Deductive reasoning starts with an existing theory, derives testable hypotheses from it, and then examines evidence to test those hypotheses.

Inductive reasoning moves in the opposite direction: it begins with observations and develops patterns, concepts, or theory from them.

Application

A quantitative strategy typically operationalizes theoretical concepts as measurable variables and tests theory-derived hypotheses with structured numerical data. Its principal theory-to-data orientation is therefore deductive.

Contrast and cross-check

• Quantitative research commonly follows the sequence theory → hypothesis → measurement → test.

• Qualitative research commonly develops contextual meanings or concepts from detailed observations, so its usual orientation is more inductive.

• Inductive names a direction of reasoning from observations toward theory; it is not the research-strategy label requested here.

• Constructive means building an account or artifact; the related term constructivism denotes a research paradigm, not this theory-testing strategy.

Thus, the strategy with the principal deductive orientation is quantitative research.
