In the deductive method, a researcher can begin the work with which of the following?

In the deductive method the work can begin with theoretical postulations, existing exploratory data and the derivation of a hypothesis.

Deduction starts from established theory, so theoretical postulations are the natural opening point.

Deriving a hypothesis from that theory sets up the specific proposition to be tested.

Available exploratory data can inform how the theory is framed before formal testing begins.

Policy statements are practical directives, not the theoretical starting material of deduction.

The social identity of the researcher is a reflexive concern, not a launching point for a deductive study.
