DEFINITION OF RESEARCH
Research comprises defining and redefining problems, formulating hypothesis or suggested solutions; collecting, organising and evaluating data; making deductions and reaching conclusions; and at last carefully testing the conclusions to determine whether they fit the formulating hypothesis. Clifford Woody
DEFINITION CONT.…
Research is defined as a systematic and objective analysis and recording of controlled observation that may lead to the development of generalisation of principles, theories, resulting in prediction and possible ultimate control of events.
J.W. Best
DEFINITION CONT.…
Research in its broadest sense is an attempt to gain solution to problem; more precisely it is a collection of data in a rigorously controlled situation for the purpose of prediction or explanations.

DEFINITION OF NURSING RESEARCH
Nursing research is a scientific process that validate and refines exciting knowledge and generate new knowledge that directly and indirectly influences clinical nursing practice.
Burns and Grove, 2005
A systematic inquiry designed to develop knowledge about issues of importance to the nursing profession, including nursing practice, education and administration and informatics.
Polit & Beck, 2005
Nursing research is a way to identify new knowledge, improve professional education and practices and use resources effectively.
International Council of Nurses, 1986
QUANTITATIVE RESEARCH
Quantitative research is based on the measurement of quantity or amount. It is applicable to phenomena that can be expressed in terms of quantity.
QUANTITATIVE RESEARCH
• Experimental Research
•Non-Experimental Research
EXPERIMENTAL RESEARCH
In this researchers actively introduce an intervention or treatment. The researcher play an active role by introducing the intervention. Researchers are active agents & not passive observers.
CHARACTERISTICS OF EXPERIMENTAL RESEARCH
•Manipulation•Control•Randomization
NON EXPERIMENTAL RESEARCH
In Non experimental research researchers are observers- they collect data without intervening.
QUALITATIVE RESEARCH
Qualitative researchers aim to gather an in-depth understanding of human behaviour and the reasons that govern such behaviour. The qualitative method investigates the why and how of decision making, not just what, where, when. Hence, smaller but focused samples are more often used than large samples.
