Advanced Learner’s Dictionary:
A careful investigation or inquiry specially
through search for new facts in any
branch of knowledge.
Redman and Mory:
A systematized effort to gain new knowledge.
Clifford Woody:

something.”
C.C. Crawford:
A systematic and refined technique of
thinking,

collects data or facts, analyses them
critically and reaches decisions based on
the actual evidence.
Significance of Research
All progress is born of inquiry. Doubt is
often better than overconfidence, for it
leads to inquiry, and inquiry leads to
invention.” Hudson’s Maxim
