The document discusses the different types of hypotheses used in research, including directional and non-directional hypotheses, declarative hypotheses that state relationships between variables, null hypotheses that state no significant differences exist, question form hypotheses used to raise research questions, alternative hypotheses that anticipate differences between variables, and predication form hypotheses that state expected principles for action research studies.

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

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.
