This document discusses the importance of reviewing related literature and studies when conducting research. It states that a review of existing materials provides the foundation for a proposed study by guiding the researcher and helping to identify a research problem or topic, understand the topic better, avoid duplicating other studies, locate additional sources of information, and design the research methodology. The document also outlines the characteristics, sources, and locations of related literature and studies that should be surveyed.

2. CHAPTER III

3. Is composed of discussions of facts
and principles to which the present study
is related. For instance, if the present
study deals with drug addiction, literature
to be reviewed or surveyed should be
composed of materials that deal with
drug addiction.
RELATED LITERATURE

4. These materials are usually printed
and found in books, encyclopedias,
professional journals, magazines,
newspapers, and other publications.

already conducted to which the present

10. Importance, Purposes,
and Functions of
Related Literature
and Studies

11. A survey or review of related
literature and studies is very important
because such reviewed literature and
studies serve as a foundation of the
proposed study. This is because related
literature and studies guide the
researcher in pursuing his research
venture.
Importance, Purposes, and Functions
of Related Literature and Studies

12. Reviewed literature and studies help
or guide the researcher in the following
ways:

13. 1. They help or guide the researcher in
searching for or selecting a better
research problem or topic. By reviewing
related materials, a replication of a similar
problem may be found better than the
problem already chosen. Replication is
the study of research problem already
conducted but in another place.
Importance, Purposes, and Functions
of Related Literature and Studies

14. 2. They help the investigator
understand his topic for research better.
Reviewing related literature and studies
may clarify vague points about his
problem.
Importance, Purposes, and Functions
of Related Literature and Studies

15. 3. They ensure that there will be no
duplication of other studies. There is
duplication if an investigation already
made is conducted again in the same
locale using practically the same
respondents. This is avoided if a survey of
related literature and studies be made
first.
Importance, Purposes, and Functions
of Related Literature and Studies

16. 4. They help and guide the researcher
in locating more sources of related
information. This is because the
bibliography of a study already conducted
indicate references about similar studies.
Importance, Purposes, and Functions
of Related Literature and Studies

17. 5. They help and guide the researcher
in making his research design especially
in:
a. the formulation of specific questions
to be researched on;
b. the formulation of assumptions and
hypotheses if there should be any;

18. c. the formulation of conceptual
framework;

20. d. the selection and application of the

e. the selection and application of

21. f. the selection and/or preparation and
validation of research instruments for
gathering data;
g. the selection and application of
statistical procedures;

22. h. The analysis, organization,
presentation, and interpretation of data;
i. The making of the summary of
implications for the whole study;
j. The formulation of the summary of
findings, conclusions, and
recommendation; and

of Related Literature and Studies

23. 6. They help and guide the researcher
in making comparison between his
findings of other researchers on similar
studies with the end in view of
formulating generalization or principles
which are the contributions of the study
to fund of knowledge.

of Related Literature and Studies

24. Characteristics of
Related Literature
and Studies

25. There are certain characteristics of
related materials that make them of true
value. Among these characteristics are:

26. 1. The surveyed materials must be as
recent as possible. This is important
because of the rapid social, economic,
scientific, and technological change.
Findings several years ago may be of little
value today because of the fast changing
life style of the people.
Characteristics of Related
Literature and Studies

27. There are exception, however.
Treatises that deal on universals or things
of more or less permanent nature may be
still be good today. There are
mathematical laws and formulas and
statistical procedures that had been
formulated a long, long time ago which
are being use today with very, very little
improvement. This is also true with
natural and physical laws. Books on
these, though written a long time ago,
are still being cited today.

28. Another exception is when a
comparison or contrast is to be made
between the conditions of today and
those of a remote past, say ten or twenty
years ago. Naturally, literature and
studies about that remote past have to be
surveyed and reviewed.

29. 2. Materials reviewed must be
objective and unbiased. Some materials
are extremely or subtly one sided, either
political, or religious, etc. Comparison
with these materials cannot be made
logically and validity. Distorted
generalizations may result.
Characteristics of Related
Literature and Studies

30. 3. Materials surveyed must be
relevant to the study. Only materials that
have some bearing or similarity to the
research problem at hand should be
reviewed.
Characteristics of Related
Literature and Studies

31. 4. Surveyed materials must have been
based upon genuinely original and true
facts or data to make them valid and
reliable. There are cases where fictitious
data are supplied just to complete a
research report (thesis or dissertation).
Of course, this kind of deception is hard
to detect and to prove. Thus, this is a real
problem to honest researchers.
Characteristics of Related
Literature and Studies

32. 5. Reviewed materials must not be
few or too many. They must only be
sufficient enough to give insight into the
research problem or to indicate the
nature of the present investigation. The
may also depend upon the availability of
related materials.
Characteristics of Related
Literature and Studies

33. Sometimes there is a paucity of such
materials. Ordinarily, form ten to fifteen
related materials re needed for a master`s
thesis and from fifteen to twenty-five for
a doctoral dissertation depending their
availability, as well as their depth and
length of discussions.

34. For an undergraduate thesis, from
five to ten may do. The numbers,
however, are only suggestive and not
imperative nor mandatory. These are only
the average numbers observed from
theses and dissertation surveyed by this
author.

35. Sources of
Related Literature
and Studies

36. The sources of related literature and
studies may include the following:

37. 1. Book, encyclopedias, almanacs, and
other similar references.
2. Articles published in professional
journals, magazines, periodicals,
newspapers, and other publications.

Literature and Studies

38. 3. Manuscripts, monographs, memoirs,
speeches, letters, and diaries.
4. Unpublished theses and
dissertations.
5. The Constitution, and laws and
statues of the land.

40. 7. Records from schools, public and
private, especially reports of their

Related Literature and Studies

44. 1. Libraries, either government, school,
or private libraries.
2. Government and private offices.

46. The last two are especially rich
depositories of related materials,
particularly unpublished master`s theses
and doctoral dissertations.
