Research Methodologies

  1. 1. ComputationalResearch Methodology Lecture No. 1
  2. 2. Recommended Readings• Dawson, Catherine, 2002, Practical Research Methods, New Delhi, UBS Publishers’ Distributors.• Kothari, C.R.,1985, Research Methodology- Methods and Techniques, New Delhi, Wiley Eastern Limited.• Kumar, Ranjit, 2005, Research Methodology-A Step-by-Step Guide for Beginners, (2nd.ed.),Singapore, Pearson Education.• Lecture notes.
  3. 3. What is Research?• Re + Search• Re = Again, Anew or Over again• Search = To examine closely and carefully• Research is a careful, systematic, patient study and investigation in some field of knowledge, undertaken to establish facts or principles.• Research is a structured enquiry that utilizes acceptable scientific methodology to solve problems and create new knowledge that is generally applicable.• Research is a process of collecting, analyzing and interpreting information to answer questions.
  4. 4. Characteristics of Research• Systematic (A logical sequence of steps)• Valid and Verifiable (Your findings are correct and may be verified by you and others)• Empirical (Conclusion drawn are based on evidence collected from real life experiences or observations)• Critical (The process of investigation must be foolproof and free from drawbacks)
  5. 5. Types of Research• Research can be classified from three perspectives: – application of research study – objectives in undertaking the research – inquiry mode employed• Classification based on application: – Pure research – Applied research
  6. 6. Types of Research (Con’d)• Pure research, basic research, or fundamental research is a research carried out to increase understanding of fundamental principles.• Pure research explain how this world operates, what makes things happen, why social relations are a certain way, and why society changes.• Pure research is the source of most new scientific ideas and ways of thinking about the world.• Pure research generates new ideas, principles and theories, which may not be immediately utilized; though are the foundations of modern progress and development in different fields.
  7. 7. Types of Research (Con’d)• Applied research is done to solve specific, practical questions and understanding of a phenomenon.• Applied research can be exploratory, but is usually descriptive.• Applied research can be carried out by academic or industrial institutions.• Often, an academic institution such as a university will have a specific applied research program funded by an industrial partner interested in that program.
  8. 8. Types of Research (Con’d)• Classification based on objectives: – Descriptive – Correlational – Explanatory – Exploratory• Descriptive research also known as statistical research, describes data and characteristics about the population or phenomenon being studied.• Often the best approach, prior to writing descriptive research, is to conduct a survey investigation.• Descriptive research deals with everything that can be counted and must have an impact to the lives of the people around you.
  9. 9. Types of Research (Con’d)• Correlational research tests for statistical relationships between variables.• The researcher begins with the idea that there might be a relationship between two variables.• She or he then measures both variables for each of a large number of cases and checks to see if they are in fact related.
  10. 10. Types of Research (Contd)• For example, imagine that a health psychologist is interested in testing the claim that people with more friends tend to be healthier. She surveys 500 people in her community, asking them how many friends they have and getting some measure of their overall health.• He or she then makes a graph showing the correlation between these two variables.
  11. 11. Types of Research (Contd)• Explanatory research attempts to clarify why and how there is a relationship between two or more aspects of a situation or phenomenon.• Explanatory research attempts to identify the actual reasons a phenomenon occurs.• An example of explanatory research would be a study that finds that Christian couples are twice as likely to divorce as Jewish couples.
  12. 12. Types of Research (Con’d)• Exploratory research is conducted into an issue or problem where there are few or no earlier studies to refer to.• The focus is on gaining insights and familiarity for later investigation.• Here data is often quantitative and statistics applies.• It is used to identify and obtain information on a particular problem or issue.
  13. 13. Types of Research (Con’d)• Classification based on inquiry mode: – Structured approach – Unstructured approach• The structured approach to inquiry is usually classified as quantitative research.• Here everything that forms the research process- objectives, design, sample, and the questions that you plan to ask of respondents- is predetermined.
  14. 14. Types of Research (Con’d)• The structured approach is appropriate to determine the extent of a problem, issue or phenomenon.• The structured approach addresses the problems such as: – how many people have a particular problem? – How many people hold a particular attitude?• The unstructured approach to inquiry is usually classified as qualitative research.
  15. 15. Types of Research (Con’d)• The unstructured approach is more appropriate to explore the nature of a problem, issue or phenomenon without quantifying it.• Common examples include: – An account of different opinions different people have about a product or an issue. – description of working condition in a particular industry.
