The purpose of research is to discover answers to questions through the application of scientific procedures. The main aim or objectives of research is to find out the truth that is hidden and has not been discovered yet. Though each research study has its own specific purpose, we may think of research objectives as falling into a number of the following broad groupings:
1. To gain familiarity with a phenomenon or to achieve new insights into it. Studies with this object in view are termed as exploratory or formulative research studies.
2. To accurately portray the characteristics of a particular individual, situation or a group. Studies with this object in view are known as descriptive research studies.
3. To determine the frequency with which something occurs or with which it is associated with. Studies with this object in view are known as diagnostic research studies.
4. To test the hypothesis of a casual relationship between variables. Such studies are termed as hypothesis-testing research studies.
