Scientific research is building of knowledge through collection of empirically verifiable facts. The term verifiable here means which can be checked by others for accuracy.

Kerlinger has defined scientific research as a "systematic controlled empirical and critical investigation of hypothetical propositions about the presumed relations among phenomena"

Three points that have been emphasized here are:

a. Investigation is research outcomes i ,e, the investigation is so ordered that investigators can have confidence in research outcomes. In other words the research situation is tightly disciplined.

b. Investigation is empirical i, e, subjective belief is checked against objective reality and

c. It is critical i, ,e the researcher is critical not of the results of his own inquiry but of the research results of others too.
