WH TS THEORETIC L
FR MEWORK?
A theoretical framework is
a conceptual model of how one theorizes the
relationships among the several factors (thevariables) that have been identified as
important to the problem.

THE NEED FOR A
THEORETICAL FRAMEWORK
The theoretical framework is the basis on which
the entire research rests.
A good theoretical framework is central toexamining the problem under investigation.

THE COMPONENTS OF THE
THEORETIC L FR MEWORK
The theoretical framework elaborates the
relationships among the variables, explains the
theory underlying these relations, and describes
the nature and direction of the relationships.
There are 5 basic features that should be
incorporated in any theoretical framework:

THE COMPONENTS OF THE
THEORETIC L FR MEWORK
1. The variables considered relevant to the study
should be clearly identif ied and labeled in the
discussions.
2. The discussions should state how two or more
variables are related to each other. This
should be done for the important relationshipsthat are theorized to exist among the variables.

THEORETIC L FR MEWORK
3. If the nature and direction of the relationships
can be theorized on the basis of the findings
from previous research, then there should be an
indication in the discussions as to whether the
relationships would be positive or negative.
4. There should be a clear explanation of whywe would expect these relationships to exist.
The arguments could be drawn from the
previous research findings.

5. A schematic diagram of the theoretical
framework should be given so that the reader
can visualize the theorized relationships.

HYPOTHESES
An hypothesis is:
An educated guess about a problems
solution.
It can be defined as a logically conjectured
relationship between two or more
variables expressed in the form of testable
statements.

THE ROLE OF
HYPOTHESES
Guide the direction of the study
Identify relevant facts
Suggest most appropriate research
design
Provide framework for organizing
resulting conclusions
