This PPT slide presentation deals with the Meaning of hypothesis, Types of hypothesis, Parameters of a good hypothesis, Importance of hypothesis, Source of hypothesis, Format of hypotheis & Formulation of testable hypothesis.

1. CHAPTER 6 Formulation of Hypothesis By Niranjan H N

2. HYPOTHESIS The word hypothesis consists of two words –Hypo+Thesis. ‘Hypo’ means tentative or subject to the verification. ‘Thesis’ means statement about solution of the problem.

3. HYPOTHESIS The word hypothesis consists of two words – Hypo+Thesis . ‘Hypo’ means tentative or subject to the verification. ‘Thesis’ means statement about solution of the problem.

4. Definition by John W. Best “A hypothesis is a statement temporarily accepted as true in the light of what is, at the time, known about a phenomenon, and it is employed as a basis for action in the search for new, truth, when the hypothesis is fully established, it may take the form of facts, principles and theories.”

5. Nature of Hypothesis: (i) Conceptual: Conceptual elements in the framework are involved in a hypothesis. (ii) Verbal statement in a declarative form: It is a verbal expression of ideas and concepts. It is not merely mental idea but in the verbal form, the idea is ready enough for empirical verification. (iii) It represents the tentative relationship between two or more variables. (iv) Forward or future oriented : A hypothesis is future-oriented. It relates to the future verification not the past facts and information. (v) Pivot of a scientific research : All research activities are designed for verification of hypothesis.

6. Importance of a Hypothesis

7. Other Importance It provides direction to research and prevent the review of irrelevant literature and the collection of useful or excess data. It sensitizes the investigator certain aspects of situation which are irrelevant from the standpoint of problem at hand. It enables the investigator to understand with greater clarity his problem and its ramification. It is an indispensable research instrument, for it builds a bridge between the problem and the location of empirical evidence that may solve the problem. It provides the investigator with the most efficient instrument for exploring and explaining the unknown facts. It provides a framework for drawing conclusion. It stimulates the investigator for further research.

8. Parameters Of A Good Hypothesis

9. Forms of Hypothesis

10. Directional Hypothesis

11. Non-Directional Hypothesis

12. Question form

13. Declarative Statement Provides an anticipated relationship or difference between variables. It is merely a declaration of the independent variables effect on the criterion variable. When researcher makes a positive statement about the outcome if the study, the hypothesis takes the declarative form Ex: There will be a significant difference in the instructional standards of Boys and girls in school

14. Null Hypothesis

15. Alternative Hypothesis

16. Logical Hypothesis

17. Predication Form Hypothesis

18. Sources of hypothesis

19. What are the key components of a hypothesis?

20. What is the format of a hypothesis?

21. Formulation of Testable Hypothesis

22. Example of Hypothesis

23. 1. Define Variables

24. Example  Will you test that rewards increase reading achievement? Or rewards decrease reading achievement?

25. 2. Study In-Depth the Variables

26. 3. Specify the nature of relationship

27. 4. Identify Study Population

28. 5. Make Sure Variables are Testable
