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.

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.”
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.
Importance of a Hypothesis

Clear and
specific goals

Prevents blind
research
Guiding light
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.

Forms of Hypothesis
DIRECTIONAL
HYPOTHESIS
NON-DIRECTIONAL
HYPOTHESIS
Directional Hypothesis
A directional hypothesis connotes an expected direction in the
relationship or difference between variables.
This type of hypothesis developer appears more certain of anticipated
evidence.
it reveals two possible conditions.
additional evidence is scarcely needed.
researcher has examined the variables very thoroughly and the
available evidence supports the statement of a particular anticipated
outcome.
Example : There will be a positive relationship between extra coaching
and academic achievements
Non-Directional Hypothesis
This hypothesis is stated in the null form which is
an assertion that no relationship or no
difference exists between or among the
variables.
Difference can be in any directions
Example : There will be a difference in
adaptability of fathers and mothers towards
rearing of their children
Question form
Simplest level of empirical
observation.
It divides hypothesis forms into
acceptable / rejectable categories
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
Null
Hypothesis
It is a negative statement.
It states that there is no relationship between
variables concerned
It can be tested statistically so it is termed as
statistical hypothesis
Also called testing hypothesis.
Denoted by H0.
EX: There is no significant change in an individual’s
work habits whether they get eight hours or nine
hours of sleep.
Alternative
Hypothesis
Denoted by H1
An alternative hypothesis is a claim
that is contradictory to the null
hypothesis. To disprove a null
hypothesis, researchers will seek to
discover an alternative hypothesis.
Work habits improve during the times
when one gets 8 hours of sleep only,
as opposed to 9 hours of sleep only.
Logical Hypothesis
A logical hypothesis is a proposed explanation possessing
limited evidence.
In reference to these examples, there is currently no
evidence to support these hypotheses. However, we can form
a hypothesis based on the data available to us to draw a
logical conclusion.
Ex: Beings from Mars would not be able to breathe the air in
the atmosphere of the Earth.
Predication Form
Hypothesis
It allows the researcher worker to
state principles which he expects to
emerge from the experiment.
It is more useful in action
research studies.

What are the key components of a
hypothesis?
If [cause], Then [effect],
Because
[rationale].
A definition of the
problem, a
proposed
solution, and a
result.
What is the format of a hypothesis?
A hypothesis often follows a basic format of:
“If {this happens} then {this will happen}.”
One way to structure your hypothesis is to describe what will
happen to the dependent variable if you make changes to the
independent variable.

• Will you test that rewards increase reading
achievement? Or rewards decrease reading
achievement?
2. Study In-

Specify independent and

Rigorous questions
Ex: you need to intense
study how rewards
increase reading
achievements?
3. Specify
the nature
of
relationship
Identify what relationship exist
between variables
What variable influence another
variable
Ex: How Rewards impact
achievements? If reward plays a
key role in reading achievements,
then reward is the independent
variable.

Target Population

research we mean the

individuals is going to

5. Make Sure
Variables are
Testable
The hypothesis would be worthless if its
cant be tested
Your research study must accept or reject a
variable.
Variables you must need to test.
Testable variables can only be accepted or
rejected.
Moreover, the sole aim of a research
hypothesis is to test variables in the long
run.
