Research, Theory, Design & Methods: Week 5 

Week 5: Quantitative Research Designs

1. Returning to the Grand Canyon panorama, a few questions come to
mind as you prepare to leave for your next trip: How should you go about
pinpointing the exact spot from which to photograph? Will changes in
the lighting make integrating new pictures into your panorama difficult?
In any case, you now have a purpose for your trip, can state your
intentions, and can identify key questions that invite a search for
answers and focus your approach to your next trip.

2. You are now at a similar point in your understanding of the
research process, such that an overall framework, including
philosophical orientation, theory, literature, problem, and purpose, is
falling into place. This week, you will continue to expand your
understanding of this framework by analyzing and evaluating research
questions and hypotheses in quantitative studies. You will also learn
about various quantitative research designs that researchers use to
answer their research questions. You will also continue to analyze the
interrelated elements of a research study, making the connection among
theory, problem, purpose and, now, research questions, hypotheses, and
design.

Learning Objectives

Students will:

· Evaluate quantitative research questions and hypotheses in research studies published in peer-reviewed journals

· Identify quantitative designs in research studies published in peer-reviewed journals

· Explain use of quantitative designs in research studies published in peer-reviewed journals

· Analyze alignment among theory, problem, purpose, research
questions and hypotheses, and design in quantitative research studies
published in peer-reviewed journals

· Apply APA Style to writing

Discussion: Evaluating Research Questions, Hypotheses, and Quantitative Research Designs

1. With a clear purpose in place, quantitative researchers have a
roadmap for crafting their research questions and hypotheses that will
further focus the approach they will take to investigate their topic
(i.e., their study’s research design).

The selection of a research design is guided by the study’s purpose
and research questions and hypotheses, and the design then links the
research questions and hypotheses to the data that will be collected.
You should keep in mind, however, that the research process is
interactive, not necessarily proceeding in a linear fashion from one
component to the next. Rather, the writing of research questions could,
for example, necessitate adjustments to the study’s purpose statement.
Nevertheless, when presented together, the various components of a
research study should align. As you learned last week, alignment means
that a research study possesses clear and logical connections among all
of its various components.

In addition to considering alignment, when researchers select a
research design, they must also consider the ethical implications of
their choice, including, for example, what their design selection means
for participant recruitment, procedures, and privacy.

· For this Discussion, you will evaluate quantitative research
questions and hypotheses in assigned journal articles in your discipline
and consider the alignment of theory, problem, purpose, research
questions and hypotheses, and design. You will also identify the type of
quantitative research design the authors used and explain how it was
implemented. Quasi-experimental, casual comparative, correlational,
pretest–posttest, or true experimental are examples of types of research
designs used in quantitative research.

· With these thoughts in mind, refer to the Journal Articles document
for your assigned articles for this Discussion. If your last name
starts with A through I, use Article A. If your last name starts with J
through R, use Article B. If your last name starts with S through Z, use
Article C.

By Day 4

Post a critique of the research study in which you:

· Evaluate the research questions and hypotheses (The Research
Questions and Hypotheses Checklist can be used as a guide to facilitate
your evaluation; it is not meant to be used in a Yes/No response format
in writing your Discussion post.)

· Identify the type of quantitative research design used and explain how the researchers implemented the design

· Analyze alignment among the theory, problem, purpose, research questions and hypotheses, and design

· Be sure to support your Main Issue Post and Response Post with
reference to the week’s Learning Resources and other scholarly evidence
in APA Style.

Read a selection of your classmates’ postings 

By Day 6

Respond to a classmate who was assigned a different article than you
by further supporting his or her critique or respectfully offering a
differing perspective.
