A general view
Ø    Hypothesis is a statement, temporarily accepted, as true in the light of what is known about a phenomenon which is proposed for further research.
Ø    It is a tentative assumption drawn from knowledge and theory which is used as a guide for investigation for other facts and theories that are yet unknown

·         A hypothesis states what we are looking for.
Ø    It is a provisional guess, which seems to:
   Explain the situation under observation
n     Definition of hypothesis
n     “Hypothesis is a tentative explanation for certain behavior, phenomenon that have occurred or will occur.
n     It is the most specific statement of the problem” (L.R. Gay 1992).
n     Hypothesis is a tentative answer to a question. (John W. Best 1982)

Forms of hypothesis

n     It states that there is no significant difference between in the two variables.

There is no significant difference in the instructional standard of single shift and double shift schools

n     This form of hypothesis allows the researcher to state principles which he actually imagine to emerge from theexperiment.

Declarative form
n     This type of hypothesis generally states the relationship between the concerned variables.
For example there will be a significant difference in the instructional standard of boys and girls schools 


n     The declarative form may be question form if we read it in the form of question.
n     Is there a significant difference in the instructional standard of boys and girls schools?

Importance of hypothesis
Ø    It provides direction to researcher
Ø    It defines what is relevant and what is irrelevant
Ø    It sensitize the researcher to certain aspects of the situation which are relevant from the problem view point.

Ø  It shows the difference between fruitful and fruitless research
Ø    It is a guide to the thinking process and the process of discovery.
Ø    It is investigator’s eyes.
Ø    It is a sort of guiding star in the world of darkness
Ø    Without hypothesis research would be like random and aimless wandering
Ø    It focuses on research and prevents blind research
Ø    It places clear and specific goals before the researcher
Ø    Continue….
Ø    It links together related facts and information and organizes them into one comprehensible whole
Ø    It is important because they have the power to predict.
Ø    It serves as a framework for drawing conclusion

Sources of hypothesis
 Deriving sufficient hypothesis is difficult than selecting of the problem.
There is no royal road to the discovery of fruitful hypothesis
n     A good investigator must have not onlyan alert mind, capable of deriving relevant hypothesis but also have a  critical mind capable of rejecting a faulty hypothesis

The following are the main sources of hypothesis
n     General culture
In the investigations for solving a problem we cannot ignore our general culture    ( religious, moral) to which we belong
n     Scientific Theory
We have to keep in mind various scientific
theories like sound body has sound mind.
Handicapped children face adjustment
problems, rest relieves fatigue
n     Personal experience
Good hypothesis can come only from
Experience; such as teacher punctuality
enhances students punctuality or good
study habit improve achievement
n     Analogies
It a very fertile source of hypothesis.it is the process of framing hypothesis from similarity and likeness, such as if a problem is similar in nature to a problem studied in a foreign country we may frame our hypothesis in the same manner

n     A good hypothesis is in agreement with the observe facts
n     A good hypothesis does not in conflict with any law of nature which is known to be true. When we say that there can be a memory tablets for strengthening memory we are trying to reject an establish law of nature.
n     A good hypothesis is stated in a scientific and research like language and is not an ordinary statement.
n     It is stated in the simplest possible terms
n     A good hypothesis permits the application of deductive reasoning
n     It should be framed so that its tests will provide an answer to the original problem.
n     Difficulties in the formulation of hypothesis
n     Lack of knowledge and clarity about the concerned area.
n     Lack of ability.
n     ambiguity of the statement
n     Testing the hypothesis
n     The worth of the validity of the hypothesis lies in its testing.
n     After formulating the hypothesis it is necessary to deduce:
n     its consequences.
n     Select or develop tools
n     Use the tool to confirm or reject the hypothesis
