Analysis, interpretation and drawing inferences 11. Report writing Background : M S Sridhar, ISRO Research Methodology 1 4 Background Man coming to grips with his environment and to understand the nature through experience, reasoning and research 1. EXPERIENCE (Subsume a number of sources of information) Personal experience, i.e., body of knowledge and skills derived from encounters and acquaintance with facts and events in his environment Experience of others Sources beyond immediate circle, i.e., authoritative sources EXPERIENCE & AUTHORITY are richly fertile sources of hypotheses, but they are common sense knowing, often based on haphazard events and use loose & uncritical manner and hence not scientific Contd... Background Contd. : M S Sridhar, ISRO Research Methodology 1 5 Background Contd. 2. REASONING Deductive (Aristotle) – From whole to part Inductive (Francis Bacon) – From number of observations Combined 3. RESEARCH Systematic, controlled, empirical & critical investigation of hypothetical propositions about the presumed relations among natural phenomena, I.e., Systematic & controlled Empirical Self-correcting Research is a combination of both experience & reasoning and must be regarded as the most successful approach to the discovery of truth (particularly in natural sciences) Part I: Introduction to Research & Research Methodology : M S Sridhar, ISRO Research Methodology 1 6 Part I: Introduction to Research & Research Methodology Synopsis 1.

Terms used Research Methodology Research Method Research Technique Research methodology Scientific method Benefits of research methodology Qualities of good research & researcher Research process Types of research What is Research ? : M S Sridhar, ISRO Research Methodology 1 7 What is Research ? A voyage of discovery; A journey; An attitude; An experience; A method of critical thinking; A careful critical enquiry in seeking facts for principles 2. An art of scientific investigation Scientific and systematic search for pertinent information on a specific topic Process of arriving at dependable solutions to problems through the planned and systematic collection, analysis and interpretation of data 3. A systematized effort to gain new knowledge; A movement from the known to the unknown Search for (new) knowledge/ facts through objective, systematic and scientific method of finding solution to a problem Implicit question + Explicit answer + data to answer the question Not synonymous with commonsense, but systematic, objective (purposeful), reproducible, relevant activity having control over some factors 4. An activity caused by instinct of inquisitiveness to gain fresh insight / find answers to question / acquire knowledge In a broad sense, everyone does research, but don’t write it up; Without trustworthy and tested published research available we are dangerously lost in the experience, opinions and hearsay Why research ? : M S Sridhar, ISRO Research Methodology 1 8 Why research ? To get a degree To get respectability To face a challenge To solve a problem To get intellectual joy To serve society by increasing standard of living in case of S&T, and by showing right path to society in case of Social and Behavioural Sciences Terms Used : M S Sridhar, ISRO Research Methodology 1 9 Terms Used 1. RESEARCH TECHNIQUE - Behaviour and instruments used in research operations Examples: Scales, recording techniques, content analysis, moving average, longitudinal / cross sectional collection of data, etc. 2. RESEARCH METHOD - Behavior and instruments used in selecting and constructing technique (a range of approaches used to gather data) Examples: Observation, questionnaire, interview, analysis of records, case study, etc. Methods are more general than techniques. Methods & Techniques are used in performing research operations, i.e.., Collection of data Statistical processing & analysis (tests) To evaluate the accuracy of the results obtained NOTE: Research techniques and research methods are almost interchangeably used Research Methodology : M S Sridhar, ISRO Research Methodology 1 10 Research Methodology A science of studying how research is done scientifically A way to systematically solve the research problem by logically adopting various steps Methodology helps to understand not only the products of scientific inquiry but the process itself Aims to describe and analyze methods, throw light on their limitations and resources, clarify their presuppositions and consequences, relating their potentialities to the twilight zone at the ‘frontiers of knowledge’ Benefits of Research Methodology : M S Sridhar, ISRO Research Methodology 1 11 Benefits of Research Methodology Advancement of wealth of human knowledge ‘Tools of the trade’ to carry out research; Provides tools to look at things in life objectively Develops a critical and scientific attitude, disciplined thinking or a ‘bent of mind’ to observe objectively (scientific deduction & inductive thinking); Skills of research will pay-off in long term particularly in the ‘age of information’ (or too often of misinformation) Enriches practitioner and his practices; Provides chance to study a subject in depth; Enable us to make intelligent decisions; Understand the material which no other kind of work can match As consumers of research output helps to inculcate the ability to evaluate and use results of earlier research with reasonable confidence and take rational decisions Doing research is the best way to learn to read and think crically Contd... Benefits of Research Methodology Contd... : M S Sridhar, ISRO Research Methodology 1 12 Benefits of Research Methodology Contd... Additional benefits in case of librarianship: Helps to understand the ‘researcher’ as a user of library Helps to learn how to use libraries & other information resources Enables critical evaluation of literature Develops special interests & skills Helps to understand attitude of others Creates awareness of special needs of research process Facilitates reference and information service Benefits of Research Assignments to Students : M S Sridhar, ISRO Research Methodology 1 13 Benefits of Research Assignments to Students Good assignments establish outcomes beyond a product to be evaluated Good assignments help students to learn about their audience Good assignments create scenarios that are rich in contextual information Good assignments provide interim readers As with any real project, good assignments give students time and a schedule of interim deadlines Scientific Method : M S Sridhar, ISRO Research Methodology 1 14 Scientific Method The method of all logically trained minds The pursuit of truth as determined by logical considerations Classifies facts, sees their mutual relation through experimentation, observation, logical arguments from accepted postulates Tenets of scientific faith 1. DETERMINISM: Events have causes that events are determined by other circumstances (i.e.. Causal links can eventually be uncovered and understood) 2. EMPIRICISM: Verifiable by observation and ‘evidence’ (data) 3. PRINCIPLES OF PARSIMONY: Phenomenon should be explained in the most economical way possible 4. GENERALITY: More problematic in social & behavioral science than natural science Basic Postulates of Scientific Method : M S Sridhar, ISRO Research Methodology 1 15 Basic Postulates of Scientific Method Relies on empirical evidence (empiricism) Utilizes relevant concepts Committed to only objective considerations Presupposes ethical neutrality Results into probabilistic predictions Methodology is made known to all for critical scrutiny and testing through replication Aims at formulating most general axioms or scientific theories Encourages rigorous, impersonal mode of procedure dictated by the demands of logic and objective procedure Qualities of Good Research : M S Sridhar, ISRO Research Methodology 1 16 Qualities of Good Research THE SCIENTIFIC METHOD EMPLOYED ENSURES: Purpose/ objectives clearly defined in common concepts Procedure enumerated to keep continuity Carefully planned design leading to objective results Complete frankness; flaws reported and their effect estimated Adequate analysis of data with appropriate methods of analysis Carefully checked data for validity & reliability Conclusions confined to those justified by the data Confidence, competence/ reputation, experience, honesty & integrity of researcher Note: 38% of papers in Nature and 25% of papers in BMJ contain one or more statistical errors; 4% of errors caused non-significant findings to be misrepresented as significant (The Economist, 5 June ’04, p 70-71) Qualities of Good Research contd.. : M S Sridhar, ISRO Research Methodology 1 17 Qualities of Good Research contd.. SYSTEMATIC - Reject the use of guessing & intuition, but does not rule out creative thinking CONTROLLED – Variables are identified & controlled, wherever possible LOGICAL - Guided by rules of logical reasoning & logical process of induction & deduction EMPIRICAL- Provides a basis for external validity to results (validation) REPLICABLE - Verified by replicating the study SELF CORRECTING - Built in mechanism & open to public scrutiny by fellow professionals contd.. Research Process : M S Sridhar, ISRO Research Methodology 1 18 Research Process 1. Selection & formulation of Research Problem 2. Literature survey 3. Development of working hypotheses 4. Research design 5. Sampling strategy or sample design 6. Pilot (quick & dirty) study 7. Data collection 8. Processing & analysis of data 9. Testing hypotheses 10. Interpretation & generalisation 11. Preparation of the report NOTE: 1. Above steps are not exhaustive, nor mutually exclusive, but a series of closely related, continuously overlapping and interdependent nonlinear steps/ actions 2. What lies ahead is hard work as well as pleasure of the hunt; some frustration, but more of satisfaction; periods of confusion, but confidence that, at the end, it will all come together Ethics of Research : M S Sridhar, ISRO Research Methodology 1 19 Ethics of Research As a profound social activity research connects us to those who will use it, to those whose research we used, through them, to the research that our sources used; Hence beyond technique, we need to think about ethics of civil communication In addition to construction of bonds within any community, ethics deal with a range of moral and immoral choices; Research challenges us to define individual moral principles; Academic researchers are less tempted to sacrifice principle for a gain than commercial researchers Plagiarism, claiming credit for results of others, misreport sources or invent results, data with questionable accuracy, concealing objections that cannot be rebutted, caricaturing or distorting opposing views, destroy or conceal sources and data important for those who follow Beyond simple moral Do not to what we should affirmatively do, i.e., concern for the integrity of the work of the community combined with narrow moral standards with the larger ethical dimension Research done in the best interests of others is also in your own Types of Research : M S Sridhar, ISRO Research Methodology 1 20 Types of Research 1. DESCRIPTIVE/ SURVEY (EX-POST FACTO) Surveys & fact-finding enquiries State of affairs as it exists No control over variables Try to discover causes (I.e., ex- post facto) 2. APPLIED Finding a solution for an immediate problem & not rigorous / flexible in application of the conditions ANALYTICAL Uses facts or information already available and analyze to make a critical evaluation FUNDAMENTAL (BASIC OR PURE) Concerned with generalizations & formulation of theory Knowledge for knowledge’s sake (I.e., pure or basic research) contd…. Types of Research contd… : M S Sridhar, ISRO Research Methodology 1 21 Types of Research contd… 3. QUANTITATIVE Measured & expressed in terms of quantity Expression of a property or quantity in numerical terms Quantitative research helps: Precise measurement Knowing trends or changes overtime Comparing trends or individual libraries / units 4 CONCEPTUAL Related to some abstract idea or theory (for thinkers & philosophers) Relies on literature QUALITATIVE Involves quality or kind Helps in having insight into problems or cases EMPIRICAL Relies on experience or observation alone, i.e.,data based research Capable of being verified by observation or experiment Experimenter has control over variables contd… Types of Research contd… : M S Sridhar, ISRO Research Methodology 1 22 Types of Research contd… 5. OTHER TYPES One time/ Cross sectional vs Longitudinal/ Developmental & Trend or prediction studies (the time domain) Field setting vs Lab / Simulation research Clinical vs diagnostic studies Exploratory vs Formulated (the degree of formulation of the problem) studies Historical studies (Greater part of it is quantitative) Content Analysis is one such quantitative method – a multipurpose method developed specifically for investigating a broad spectrum of problems in which the contents of communication serve as a basis of inference. Example: word usage rates, word counts, etc. Correlational research Conclusion oriented or decision oriented research Categorization of Research Design (Design Typology Criteria) : M S Sridhar, ISRO Research Methodology 1 23 Categorization of Research Design (Design Typology Criteria) 1.
