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.
