HYPOTHESES
Hypothesis is usually considered as the principal
instrument in research. Its main function is to suggest new experiments
and observations.
DEFINITION:
Hypotheses is generally defined as “an assumption
or some supposition to be proved or disproved”. But for a researcher
hypotheses is a formal question that he intends to resolve. Goode and Hatt have
defined Hypothesis as a” proposition which can be put to test to determine
validity”
NEED
·
It
provides direction to research and prevent collection of irrelevant data.
·
It
enables the investigator to classify the information.
·
It
ensures the collection of data necessary to study the problem.
CHARACTERISTICS
·
Hypothesis
should be clear and precise
·
Hypothesis
should be capable of being tested
·
Hypothesis
should state relationship between variables, it if e
·
Hypothesis
should be limited in scope and specific.
·
Hypothesis
should activated be simple in terms, so that it is easily understandable by all
the concerned.
·
Hypothesis
should be in consistent with most known facts.
·
Hypothesis
should be amendable to testing with a reasonable time.
·
Hypothesis
must explain the facts given to the need for explanation.
FUNCTIONS
·
To
test theory
·
To

·
To

TYPES
·
Correlative Hypothesis: Correlative hypothesis is statement of relationship between
two concepts. For
example there is a relationship between age and political awareness.
·
Null Hypothesis:A null hypothesis states that there is no significant
difference between two parameters. Parameter refers to the population value referred from ample
value.
·
Alternative Hypothesis: An alternative hypothesis states that there is a significant difference between two parameters.
DIFFICULTIES IN FORMULATION OF HYPOTHESIS
·
Lack of clear theoretical background:Hypothesis do not have a clear cut and definite
theoretical background. Because of this weakness it is not easy to arrive at
certain conclusions.
·
Lack of Logical Background:it also lacks the logical use of the theoretical background.
·
Lack of knowledge of Scientific Methods:It is always not possible to have complete
information of and acquaintance with the scientific methods of formulation of
hypothesis. This lack of scientific knowledge presents difficulty in
formulation of hypothesis.
