It helps to solve the problems facing the world today such as overpopulation, pollution, drought, floods and disease. 3/18/2015
- 8. Quantitative Research Quantitative research includes designs, techniques and measures that produce discrete numerical or quantifiable data. E.g Research that consists of the percentage amounts of all the elements that make up Earth's atmosphere. Qualitative Research Qualitative research deals with designs techniques and measure that do not produce discrete numerical data. The techniques used in research are In depth Interviews, Sentence Completion Test and Story Completion Test. 3/18/2015

- 12. Quantitative Approach It involves the generation of data in quantitative form which can be subjected to accurate quantitative analysis in a formal and rigid fashion. Quantitative approach can be further sub-classified into Inferential Approach Experimental Approach Simulation Approach 3/18/2015
- 13. Quantitative Approach Inferential Approach The purpose of inferential approach to research is to form a data base from which to infer characteristics or relationships of population. This usually means survey research where a sample of population is studied (questioned or observed) to determine its characteristics, and it is then inferred that the population has the same characteristics. 3/18/2015

Editor's Notes
- Research is a process of steps used to collect and analyze information to increase our understanding of a topic or issue". It consists of three steps: Pose a question, collect data to answer the question, and present an answer to the question.
- The purpose of research is to discover answers to questions through the application of scientific procedures. The main aim of research is to find out the truth which is hidden and which has not been discovered as yet. Though each research study has its own specific purpose, we may think of research objectives as falling into a number of 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 portray accurately 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 something else (studies with this object in view are known as diagnostic research studies); 4. To test a hypothesis of a causal relationship between variables (such studies are known as hypothesis-testing research studies).
- Descriptive research attempts to determine, describe, or identify what is. It uses description, classification, measurement and comparison to describe a situation. The main characteristic is that the researcher has no control over the variables. He only reports the situation as it is at the time. The term ex-post facto is usually used for descriptive research studies in social sciences. The survey method is commonly used in descriptive research. Analytical research attempts to explain why and how. It usually concerns itself with cause–effect relationships among variables. The researcher attempts to analyze the situation and make critical evaluation.
- Basic and applied research Basic research (also called fundamental or pure research) is mainly concerned with generalizations and the formulation of theory. It is driven by curiosity or interest in a subject. The main motivation is to expand man’s knowledge, not to create or invent something. Many scientists believe that basic research lays the foundation for the applied research that follows. Applied research is designed to solve practical problems of the society. It can be argued that the goal of applied research is to improve the human condition. An example of applied research could be a study to find out how the school feeding programme has affected school enrolment rates in drought-prone districts. Applied research is increasingly gaining favour as it is helps to address the problems facing the world today such as overpopulation, pollution, depletion of natural resources, drought, floods, declining moral standards and disease. Action research is a unique form of applied research. It is a reflective process of progressive problem solving. It is also called "practitioner research" because of the involvement of the actual practitioner in real life. Action implies that the practitioner is involved in the collection of data, analysis, and the interpretation of results. He or she is also involved in implementing results of the research and is thus well placed to judge the effectiveness of the interventions.
- Quantitative vs. Qualitative: Quantitative research is based on the measurement of quantity or amount. It is applicable to phenomena that can be expressed in terms of quantity. Qualitative research, on the other hand, is concerned with qualitative phenomenon, i.e., phenomena relating to or involving quality or kind. For instance, when we are interested in investigating the reasons for human behaviour (i.e., why people think or do certain things), we quite often talk of ‘Motivation Research’, an important type of qualitative research. This type of research aims at discovering the underlying motives and desires, using in depth interviews for the purpose. Other techniques of such research are word association tests, sentence completion tests, story completion tests and similar other projective techniques. Attitude or opinion research i.e., research designed to find out how people feel or what they think about a particular subject or institution is also qualitative research. Qualitative research is specially important in the behavioural sciences where the aim is to discover the underlying motives of human behaviour. Through such research we can analyse the various factors which motivate people to behave in a particular manner or which make people like or dislike a particular thing. It may be stated, however, that to apply qualitative research in practice is relatively a difficult job and therefore, while doing such research, one should seek guidance from experimental psychologists.
- Conceptual research is that related to some abstract idea(s) or theory. It is generally used by philosophers and thinkers to develop new concepts or to reinterpret existing ones. On the other hand, empirical research relies on experience or observation alone, often without due regard for system and theory. It is data-based research, coming up with conclusions which are capable of being verified by observation or experiment. We can also call it as experimental type of research. In such a research it is necessary to get at facts firsthand, at their source, and actively to go about doing certain things to stimulate the production of desired information. In such a research, the researcher must first provide himself with a working hypothesis or guess as to the probable results. He then works to get enough facts (data) to prove or disprove his hypothesis. He then sets up experimental designs which he thinks will manipulate the persons or the materials concerned so as to bring forth the desired information. Such research is thus characterised by the experimenter’s control over the variables under study and his deliberate manipulation of one of them to study its effects. Empirical research is appropriate when proof is sought that certain variables affect other variables in some way. Evidence gathered through experiments or empirical studies is today considered to be the most powerful support possible for a given hypothesis.
