2. Types of Hypotheses
Directional Hypotheses.
Non Directional Hypotheses.

3. DIRECTIONAL HYPOTHESIS
 The hypothesis which stipulates the
direction of the expected differences or
relationship.
 Directional hypothesis is a statement of
conjuncture where the two variables of the
study are expressed as having some
relationship in a certain direction.
Example; There will be a positive relationship
between extra coaching and academic
achievement.

4. NON DIRECTIONAL HYPOTHESIS
 A research hypothesis which does not
specify the direction of expected difference or
relationships is a non directional research
hypothesis.
 In this case the difference can be in any
direction.
Example; There will be a difference in
adaptability of fathers and mothers towards
rearing of their children.

5. On the basis of types
Declarative hypothesis
Null hypothesis
Question form
Prediction form

6. Declarative Form
 It generally states a relationship between the
variables concerned.
 When the researcher makes a positive statement
about the outcome if the study, the hypothesis takes
the declarative form.
 Example;There will be a significant difference in the
instructional standards of boys and girls in schools.

7. Null Hypotheses
 The null hypothesis is the negative statement.
 It states that no significant difference exists
between the variables concerned.
 Null Hypothesis can be tested statistically. So it is
termed as statistical hypothesis.
 When declarative hypothesis tested statistically by
converting them to null form they are also called
testing hypothesis.

8. Question Form Hypotheses
 Researcher having finalized their problem of
research, raise certain questions which must
be answered through their research.
 Research questions are generally called
interrogative hypothesis.

9. Alternative Hypotheses
 It is one in which a difference between two or
more variables is anticipated by the
researcher.
 It can be non directional or directional.

10. Predication Form Hypotheses
 It is chosen because it allows the research worker to
state principles which he actually expects to emerge
from the experiment.
 It is more useful action research studies.
