  1. 1. SELECTION AND FORMATION OF RESEARCH PROBLEM JISMI JOHN ASSISTANT PROFESSOR DEPT OF SOCIAL WORK GASC
  2. 2. • It is the 1st step in research • The term ‘problem’ means a question or issue to be examined. • The nature of the problem to be selected depends upon the level at which the research is done.
  3. 3. SOURCES OF PROBLEMS 1. Reading 2. Academic experience 3. Daily experience 4. Exposure to the field experience 5. Consultations 6. Brain storming 7. Research 8. intuition
  4. 4. • Reading: Reading of books and articles relating to the subject of our interest, questions may arise in our mind. • Academic experience: classroom lectures,discussions, seminar discussions etc • Daily experience: We can get questions or ideas from daily life experiences. • Exposure to field situations: field visit, internship training and extension work provide exposure to practical problems for study.
  5. 5. • Consultation: Discussion with experts, researchers, administrators and business executives will help to identify meaningfil problem for research. • Brain storming: Discussion within a group of interested person may help to identify the problem. • Research: research on one problem may suggest problem for further research. • Intuition: sometimes new ideas may strike to one’s mind like flash.
  6. 6. PROCESS OF IDENTIFICATION • 1. Selection of the discipline : the discipline or subject in which one proposes to do research may be selected. Eg social work, economics, management, psychology etc. • 2. Demarcating the broad area or a particular aspect of the selected subject : the second step is to select a particular aspect of the selected subject. Eg if the selected subject is social work , then one may select community organisation or social welfare etc as a specific area.
  7. 7. • Identifying two or more specific topics in the selected broad area : This is the final step in identification of the problem. This requires a grasp of the branch of the subject as a whole and awareness of work already done on it.
  8. 8. CRITERIA OF SELECTION • 1. Internal(personal) criteria or factors • 2. External criteria or factors • INTERNAL CRITERIA • 1. Researcher’s interest • 2. Researcher’s competence • 3. Researcher’s own resource : finance and time
  9. 9. • EXTERNAL FACTORS • 1. Researchability of the problem • 2. Importance and urgency • 3. Novelty or originality • 4. Feasibility • 5. Facilities • 6. Usefulness and social relevance • 7. Research personnel
  10. 10. FORMULATION OF THE RESEARCH PROBLEM • Formulation means translating and transforming the selected research problem into a scientifically researchable question. • Three principal components • 1. The originating question(what one wants to know?) • 2. The rationale (why aspects?) • 3. Specifying question
  11. 11. FORMULATION PROCESS • 1. Developing title :- The title should be carefully worded. It should indicate the core of the study , reflect the real intension of the researcher, and shows what is focus. The title may also indicate the geographical area of the study. • 2. Building a conceptual model :- On the basis of our theoretical knowledge of the phenomenon under study, the nature of the phenomenon, its properties/ elements and their inter relations should be identified and structured into a framework. This conceptual model gives an exact idea of the research problem. It serves as a basis for the formulation of the objective, hypothesis of the study.
  12. 12. • 3. Defining the objective of the study :- The objectives refer to the Questions to be answered through the study. They indicate what we are trying to get from the study. The objective are derived from the conceptual model. • 4. Setting investigative questions :- Once the objectives of the research have been identified, the formulation moves to the next level, ie, investigative Questions. These sub questions are set up for each of the major research objectives/ questions.
  13. 13. • 5. Formulation of hypothesis :- The hypotheses are tentative propositions relating to investigative questions. We formulate them to be tested in our research. • 6. Operational definition of concepts :- The next step in the formulation process is to define operationally the concepts involved in the title, objectives, investigative questions and hypothesis. The operational definitions specify the measurement parameters of the variables
  14. 14. • 7. Delimiting the scope of the study :- This means demarcation of the scope and dimensions of the study. A complete study of any phenomenon is not manageable
  15. 15. CONCEPTS • A concept is an abstract symbol representing an object or a certain phenomenon, e.g., book, person, intelligence, and meeting. • A concept is in reality a definition in short hand of a class or group of facts. • Concepts are useful for constructing assumptions. The two or more concepts leads to the generation of assumptions. The combination of a number of assumptions into a system lead to the construction of formal theories.
  16. 16. CHARACTERISTICS OF CONCEPTS • 1. Concepts are symbols which we attach to the bundle of meanings we hold. • 2. Concepts represent only one part of reality. • 3. Different people hold different concepts of the same thing. • 4. Concepts also represent various degree of abstraction.
  17. 17. TYPES OF CONCEPTS • a) Concrete concepts:- Symbolize material objects which can be seen, touched and felt eg. Book , table, building • b) Abstract concepts refer to properties or characteristics of objects. eg. weight, height, attitude, intelligence, leadership
  18. 18. STEPS IN OPERATIONALISATION OF CONCEPTS • 1. Examine the definition of concepts • 2. Discover the various usage of concepts • 3. Identify the measurement criteria • 4. Formulate a tentative definition • 5. Submit the definition to as wide a critical appraisal as possible. • 6. Make final revision on the basis of the criticism received • 7. Examine the degree of congruence.
  19. 19. HYPOTHESES • The formulation of hypotheses or propositions as to the possible answers to the research questions is an important step in the process of formulation of the research problem. • Hypothesis is a tentative proposition formulated for empirical testing. It is a declarative statement combining concepts. • It is a tentative answer to a research question.
  20. 20. TYPES OF HYPOTHESES 1. Descriptive hypotheses These are propositions that describe the characteristics (such as Size, form or distribution) of a variable. The variable may be an object, person, organisation, situation or event. Example: The rate of unemployment among arts graduate is higher than that of commerce graduates.
  21. 21. 2. Relational hypotheses These are propositions, which describe the relationship between two variables. The relationship suggested may be positive or negative correlation or causal relationship. Example : Families with higher incomes spend more for recreation.
  22. 22. 3. Causal hypotheses It state that the existence of, or a change in, one variable causes or leads to an effect on another variable. The first variable is called the independent variable, and the latter the dependent variable.
  23. 23. 4. Working hypotheses While planning the study of a problem, hypotheses are formed. Initially the may not be very specific. In such cases, they are referred to as working hypotheses which are subject to modification as the investigation proceeds.
  24. 24. 5. Null hypotheses A null hypothesis is a hypothesis that says there is no statistical significance between the two variables in the hypothesis. the most valuable hypothesis for the scientific method because it is the easiest to test using a statistical analysis. Testing the null hypothesis can tell you whether your results are due to the effect of manipulating the dependent variable or due to chance.
  25. 25. 6. Statistical hypotheses The are statement about a statistical population. These are derived from a sample. These are quantitative in nature in that they are numerically measurable. Example: Group A is older than Group B
  26. 26. SOURCES OF HYPOTHESES • 1. Theory :- this is one of the main sources of hypotheses. Logical deduction from theory leads to new hypotheses. • 2. Observation :- Hypotheses can be derived from observation. • 3. Analogies:- it is another source of useful hypotheses. • 4. Intuition and personal experience :- It may also contribute to the formulation of hypotheses. Personal life and experiences of persons determine their perception and conception.
  27. 27. • 5. Findings of studies: - Hypotheses may be developed out of the findings of other studies in order to replicate and test. • 6. State of knowledge :- An important source of hypotheses is the state of knowledge in any particular science. Where formal theories exist, hypotheses can be deduced. If the hypotheses are rejected, theories would be modified. • 7. Culture:- Another source of hypotheses is the culture on which the researcher was nurtured. • 8. Continuity of research:- The continuity of research in a field itself constitutes an important source of hypotheses
  28. 28. THE FUNCTIONS OR THE ROLE OF HYPOTHESES • 1.. A hypotheses gives a definite point to the investigation, and it guides the direction on the study. • 2. It specifies the sources of data, which shall be studied, and in what context they shall be studied. • 3. It determines the data needs. It defines which facts are relevant and which are not. • 4. A hypotheses suggests which type of research is likely to be most appropriate • 5. It determines the most appropriate technique of analysis. • 6. It contribute to the development of theory.
  29. 29. CHARACTERISTICS OF A GOOD HYPOTHESIS • 1. Conceptual clarity • 2. Specificity • 3. Testability • 4. Availability of techniques • 5. Theoretical relevance • 6. Consistency • 7. Objectivity • 8. Simplicity
  30. 30. IDENTIFICATION OF VARIABLES • A variable is defined as anything that has a quantity or quality that varies. • Variable is also known as a concept that can be measured. • A concept cannot be measured while a variable can be subjected to measurement by units of measurement, whether subjective or objective.
  31. 31. TYPES OF VARIABLES • 1. Independent and Dependent Variable: Independent variable is the major variable the researcher wishes to investigate. It is the variable which is selected, manipulated and measured by the researcher. An independent variable (also called X variable in statistics) is one whose change results in the change of another variable. The dependent variable (also called Y variable in statistics) on the other hand is the condition researcher is trying to explain. It is one which changes in relationship to changes in another variables(s).
  32. 32. • 2. Experimental and Measured Variable: • The experimental variables spell out the details of the investigator’s manipulations while the measured variables refer to measurement. • 3. Discrete and Continuous Variable: • A discrete variable is a variable having only integer value. Any variable that is not restricted to particular values (other than limited by the accuracy of the measuring instrument) is known as continuous variable.
  33. 33. • Quantitative and Qualitative Variables: The quantitative variable is one whose values or categories consist of numbers and if differences between its categories can be expressed numerically. Examples of quantitative variables include age, income, size and so forth. The qualitative variable is one which consists of discreet categories rather than numerical units. This variable has two or more categories that are different from each other. For examples sex (male of female), religion (Hindu, Jain, Muslim,Sikh), caste (General, OBC, SC, ST).
