INDUCTIVE METHOD OF RESEARCH

INDUCTIVE METHOD OF RESEARCH

Inductive method of research :

Induction is the most frequently used method of scientific research. Induction is a

process of reasoning from particular cases to whole group of cases from specific

instances to general rules. The inductive method is also known as historical, empirical

and a posseriori method, It tries to remove the gulf between theory and practice. This

method examines various causes one after another and tries to establish casual

relations between them. General principles are laid down after examining a large

number of special instances or facts. The method is said to be ‘empirical’ because the

formulation of principle is made only after an extensive indicative argument does not

establish the conclusion conclusively. The premise of a valid argument may be true, but

the conclusion may still be false. Its premise only supports the conclusion but it does not

make the latter certain.

1. More realistic: This method is more realistic because it studies the changes in

2. Possibility of verification: The method is more useful because its prepositions can be

some conclusions out of them. The cost is too much for him.

of the physical science. In socio-legal studies, we study a man’s problems. As such

the method has limited used.

If anyone asks which method is preferred, the answer is both. Prof. Marshall says

“Induction and deduction are both needed for scientific study as right and left foot for

walking.

Induction operates on faith that in the course of things for a long time is a basic

and regularity evidenced. Surely enough for the inference that it will continue in the

future. If the premise and conclusion in the logical case, are both known, some

probability relations maybe established between them and this may serve as a

paradigm of an inductive inference. Inductive explanations also have explanandum and

explanans. The explanandum is generally probable. Explanandum cannot be deducted

from the explanans with certainty. The explanadnum is implied by the explansns. The

explanans support or provide evidence for the explanandum but does not make the

latter certain. The explanans can be true and the explanandum can be false in inductive

explanations. Inductive explanations explain either the probability of individual evens or

statistical generalizations.

Inductive examines the particular phenomena and discovers from them the

general law. There are two laws which binds the process of induction, i.e., the law of

universal causation and the law of uniformity of nature. Perfect induction is a method of

arriving at a universal proposition after taking into consideration of all the individual

instances of phenomena under investigation.

Induction argument derives a generalized conclusion on the basis of particulars

which are often empirically derived observations. The premise of an inductive argument

makes the conclusion probable, not certain. The inductive approach relies on the

scientific discovery of facts. One characteristic of inductive argument is that it

establishes a conclusion with a content which goes beyond its premise. From the

observation of sample, an inference is made about a whole population. This is called

the ‘inductive leap’, jumping from the premise, which relates to an observed sample, to

the conclusion which concerns with entire population. The greater the number of

representative units in the premise of observed in the sample, the smaller is the

inductive leap. The premise of a heap of fats. Better than either the spider or an ant is

the bee, which selectively gathers pollen and transforms it into honey. To be a bee, one

has to mingle both induction and deduction in intricate way.

The combination of induction and deduction is necessary for obtaining true

knowledge because the testing of the truth or validity of a set of propositions depends

upon demonstrating that the consequences deduced from those propositions are

observable.

Through observations and inductive reasoning we accumulate knowledge

consisting of facts, concepts and empirical generalizations. This is not necessarily true

knowledge. The next step makes use of deductive reasoning. In this step a theoretical

model is constructed from known generalizations and other assumptions, the

hypotheses are deduced from the mode, Hypotheses are propositions  which are

deduced from theoretical models and whose truth has be tested through observation.

The process of constructing the theoretical model and deducing hypotheses from it is

entirely based on reasoning. To complete the study, however, hypotheses have now to

be tested through observation. If the hypotheses are validated then it is to be accepted

that the theoretical model from which the hypotheses have been deduced is also true. It

then becomes part of the theoretical knowledge or true knowledge. Thus we succeed in

acquiring knowledge about the true reality through an investigation of the empirical

reality.

The above approach of study starts with induction, is followed with deduction and

then ends up, again with induction. Studies need not always begin with observation. If

there are already a sufficient number of tested propositions, one can straightaway

formulate a theoretical model and deduce hypotheses and then test the hypotheses with

observation. This approach of study starts with reasoning (deduction) and ends up with

observation (induction). However, in either of these approaches both induction and

deduction are involved.
