- PSY 325 Week 3 Assignment Final Paper Outline
- Final Paper Topic Proposal. For the Final Paper,
you will identify three to five research studies
from peer-reviewed sources that were published
within the last ten years, which investigate a
particular social science problem or topic. The
Final Paper will focus on critiquing the varying
statistical approaches used in each of these
studies.

- ASHFORD PSY 325 Week 1 DQ 1 Types of Data
- ASHFORD PSY 325 Week 1 DQ 2 Measures of
Variability and Central Tendency
- Types of Data. Give an example of a research
question that includes an independent and a
dependent variable. These are usually presented
as, "How does A affect B?", where A is your
independent variable and B is your dependent
variable. Describe the independent and dependent
variables in terms of whether they are nominal
(also called categorical), ordinal, interval, or
ratio variables (interval or ratio variables are
also called continuous variables). How would you
study this research question?
- Measures of Central Tendency. For this
discussion, come up with 20 different data points
(set of data) and enter them into the first
column in an Excel spreadsheet. The data points
can be any numbers you want as long as there are
20 of them. Your set of data should reflect one
of the following criteria - Create a set of data for which the mean is
greater than the median.

- ASHFORD PSY 325 Week 2 Assignment Article Summary
- ASHFORD PSY 325 Week 2 DQ 1 Graphs
- Article Summary. For your Final Paper you will
identify three to five quantitative research
studies from peer-reviewed sources which were
published within the last ten years and that
investigate a particular social science problem
or topic. The Final Paper will focus on
critiquing the varying statistical approaches
used in each of these studies and assess the
strengths and weaknesses of each as it relates to
the study of the problem or topic identified.
- Graphs. Give one example of health-related data
(a variable) that can be represented by a pie
chart. Do the same for a bar chart and a
histogram. Explain why each data example you
selected (there will be a total of three
different variables) is well represented by the
corresponding graph.

- ASHFORD PSY 325 Week 2 DQ 2 Standard Normal
Distribution
- ASHFORD PSY 325 Week 3 Assignment Final Paper
Outline
- Standard Normal Distribution. Review Chapter 3 of
your course text, which introduces probability
and the standard normal distribution. When
comparing data from different distributions, what
is the benefit of transforming data from these
distributions to conform to the standard
distribution? What role do z-scores play in this
transformation of data from multiple
distributions to the standard normal
distribution? What is the relationship between
z-scores
- Final Paper Outline. This week, your assignment
is to prepare an outline for the Final Paper that
is due next week. Review the Final Paper
requirements, which are located in Week Five of
your course or in the Components of Course
Evaluation section of this guide.

- ASHFORD PSY 325 Week 3 DQ 1 Choose the Analysis
- ASHFORD PSY 325 Week 3 DQ 2 Repeated Measures
- Choose the Analysis. A researcher wishes to study
the effect of a new drug on blood pressure. Would
you recommend using a z-test, a t-test, or an
A.N.O.V.A. for the analysis? Explain your answer.
What would your choice of test depend on? For the
test you select, explain your design and your
comparison groups. Would the hypothesis be
directional or non-directional? Would the test be
one-tailed or two-tailed? What would be the null
and what would be the alternative hypothesis?
- Repeated Measures. Review Chapter 7 of your
course text, which reviews inferential statistics
that analyze experiments of repeated measures
designs. For this discussion, search the
University Library and find a scholarly,
peer-reviewed study on any behavioral or social
sciences topic that used a repeated measures
design. Reference the study and summarize the
research question, the subjects, and the
variable(s) of interest. What statistical
analysis was used and what were the results? Were
there any statistically significant differences?

- ASHFORD PSY 325 Week 4 DQ 1 Correlation
- ASHFORD PSY 325 Week 4 DQ 2 Regression
- Regression. Explain the relationship between
correlation and regression. What do the two
approaches have in common, and how are they
different? In what types of research might one
approach be preferred over the other? Explain and
justify your response. Be sure that your
discussion refers to both predictor and criterion
variables as well as their role in the regression
equation.
- Correlation. Much has been written about the
relationship between a students S.A.T. test
scores and their familys income. Generally
speaking, there is a strong positive correlation
between income and S.A.T. scores. What might this
tell you? Is this evidence that having a high
family income causes one to have high S.A.T.
scores? Is this evidence that high S.A.T. scores
are a cause of high income? Or, does this tell
you something else?

- ASHFORD PSY 325 Week 5 DQ 1 Chi
- ASHFORD PSY 325 Week 5 DQ 2 Chi
- Chi-Square Test of Independence. Describe the
chi-square test of independence. Give an example
of a question that could be answered using this
test. If you were to assemble a contingency
table, what would be included in your rows and
columns? Pick a cell of this contingency table
and explain what the value in the cell would
represent (you do not need to give the value,
just explain what it would represent)? What
hypothesis would be tested? What do you think the
answer would be? Why?
- Chi-Square Goodness-of-Fit Test. Describe the
chi-square goodness-of-fit test. Provide a
detailed explanation of what this test measures,
and how it is similar to and different from the
independent t-test. How do you know when to use
one analysis over the other? Provide a real-world
example.

- ASHFORD PSY 325 Week 5 Final Paper
- For your Final Paper you will conduct a research
study critique. Utilize the instructor-approved
topic that you selected in Week One of the
course. Identify three to five quantitative
research studies from peer-reviewed sources which
were published within the last ten years that
investigate this topic. Describe the statistical
approaches (i.e., identify the variables and
their type) used in each study and the
interpretation of the results. Finally, present
other statistical approaches that could have been
used and, when appropriate,
