7.3 The Mechanics
of Writing a Research Report
Beginning researchers may find the writing style used for
research reports awkward or unaesthetic, but there is a definite
purpose behind the rules governing scientific writing: clarity.
Every effort must be made to avoid ambiguity.
Given the wide variety of approaches to research, it stands to
reason that the approaches to writing a research report are
equally varied. Most research reports, however, include only
five basic sections or chapters: introduction, literature
review, methods, results, and discussion.
7.3.1
Introduction
The
introduction should alert the reader to what is to follow. Most
introductions usually contain the following:
1.
Statement of the problem. The first job of the
report writer is to provide some information about the
background and the nature of the problem under investigation. If
the research topic has a long history, then a short summary is
in order. This section should also discuss any relevant
theoretical background that pertains to the research topic.
2.
Justification. Another important area to be covered in
this initial section is the rationale and justification for the
project. This section should address the question of why it is
important for us to spend time and energy researching this
particular problem. Research can be important because it deals
with a crucial theoretical issue, because it has practical
value, or because it has methodological value.
3.
Aims of the current study. Most
introductory sections conclude with an unequivocal statement of
the hypothesis or research question to be answered by the study.
7.3.2
Literature Review
The second major section is the review of the literature.
In some formats, the literature review is incorporated into the
introduction. As the name suggests, the literature review
section briefly recapitulates the work done in the field. This
review need not be exhaustive; the writer should summarize only
those studies most relevant to the current project. All
literature reviews should be accurate and relevant.
1. Accuracy
A
concise and accurate distillation of each study in your review
is a prerequisite for any literature review. The main points of
each study—hypotheses that were tested, sample, method,
findings, and implications— should be briefly summarized. The
review should be selective but thorough.
2. Relevance
A
literature review should be more than a rote recitation of
research studies. It must also contain analysis and synthesis.
The writer is obligated to discuss the relevance of the past
work to the current study. What theoretic development can be
seen in past work? What major conclusions have recurred? What
were some common problems? How do the answers to these questions
relate to the current study? The ultimate aim of the review is
to show how your study evolved out of past efforts and how the
prior research provides a justification for your study.
7.3.3 Methods
The
methods section describes the approach used to confront the
research problem. Some of the topics that are usually mentioned
in this section are as follows.
1.
Variables used in the analysis
This includes a description of both independent and dependent
variables, explaining how the variables were selected for the
study, what marker variables, if any, were included, and how
extraneous variables were controlled. Each variable also
requires some justification for its use — variables cannot be
added without reason. The mean and the standard deviation for
each variable should be reported when necessary.
2. Sample size
The
researcher should state the number of subjects or units of study
and also explain how these entities were selected. Additionally,
any departure from normal randomization must be described in
detail.
3. Sample characteristics
The
sample should also be described in terms of its demographic,
lifestyle, or other descriptor characteristics. When human
subjects are used, at least their age and sex should be
indicated.
4. Methodology
Every
research report requires a description of the methods used to
collect and analyze data. The amount of methodological
description to be included depends on the audience; articles
written for journals, for instance, must contain more detailed
information than reports prepared in private sector research.
5. Data manipulation
Often
the collected data are not normally distributed, and researchers
must use data transformation to achieve an approximation of
normality. If such a procedure is used, a full explanation
should be given.
7.3.4 Results
The
results section contains the findings of the research. It
typically contains the following:
1. Description of the analysis
The
statistical techniques used to analyze the data should be
mentioned. If the analysis used common or easily recognized
statistics, a one-sentence description might be all that is
needed, such as "Chi-square analyses were performed on the data"
or "Analysis of variance was performed….."If appropriate, the
particular statistical program used by the researcher should be
identified. Finally, this part should include an overview of
what is to follow: "This section is divided into two parts. We
will first report the results of the analysis of variance and
then the results of the regression analysis."
2. Description of findings
The
findings should be tied to the statement of the hypotheses or
research questions mentioned in the introduction. The author
should clearly state whether the results supported the
hypotheses or whether the research questions were answered.
Next, any peripheral findings can be reported. Many researchers
and journal editors suggest that interpretation and discussion
of findings be omitted from this section and that the writer
should stick solely to the bare facts. Others think that this
section should contain more than numbers, suggesting the
implications of the findings as well. In fact, for some short
research articles, this section is sometimes called "Findings
and Discussion." The choice of what model to follow depends upon
the purpose of the report and the avenue of publication.
3. Tables
Tables,
charts, graphs, and other data displays should be presented
parsimoniously and, if the article is being submitted to a
journal, in the proper format. Remember that many readers turn
first to the tables and may not read the accompanying text;
consequently, tables should be explicit and easily understood by
themselves.
7.3.5 Discussion
The
last section of a research report is the discussion. The
contents of this section are highly variable but the following
elements are common.
1. Summary
A
synopsis of the main findings of the study often leads off this
section.
2.
Implications/discussion/interpretations
This
is the part of the report that discusses the meaning of the
findings. If the findings are in line with current theory and
research, the writer should include a statement of how they
correspond with what was done in the past. If the findings
contradict or do not support current theory, then some
explanation for the current pattern of results is provided.
3. Limitations
The
conclusions of the study should be tempered by a report of some
of its constraints. Perhaps the sample was limited or the
response rate was low or the experimental manipulation was not
as clean as it could have been. In any case, the researcher
should list some of the potential weaknesses of the research.
4.
Suggestions for future research
In
addition to answering questions, most research projects uncover
new questions to be investigated. The suggestions for research
should be relevant and practical. |
