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"
