•  
• PSY 325 Week 1 Assignment Final Paper Topic
  Proposal 
• 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.
• Your assignment this week is to identify the
  topic that you intend to focus on for your Final
  Paper. You may select any social science problem
  or topic however, it must be something that has
  been studied using quantitative research methods.
  Some examples of possible topics include

•  
• PSY 325 Week 1 DQ 1 Types of Data 
• 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?

• PSY 325 Week 1 DQ 2 Measures of Variability and
  Central Tendency 
• 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.

• PSY 325 Week 2 Assignment Article Summary 
• 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.

•  
• PSY 325 Week 2 DQ 1 Graphs 
• 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.

PSY 325 Week 2 DQ 2 Standard Normal Distribution

• For more course tutorials visit
• www.uophelp.com
•  
• PSY 325 Week 2 DQ 2 Standard Normal Distribution 
• 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 and percentages? In your opinion, does
  one do a better job of representing the
  proportion of the area under the standard curve?
  Give an example that illustrates your answer.

PSY 325 Week 3 DQ 1 Choose the Analysis

•  
• PSY 325 Week 3 DQ 1 Choose the Analysis 
• 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? 

11
PSY 325 Week 3 DQ 2 Repeated Measures

• For more course tutorials visit
• www.uophelp.com
•  
• PSY 325 Week 3 DQ 2 Repeated Measures 
• 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?
  What does it mean for the results to be
  statistically significant? What does this mean
  specifically for the differences assessed in this
  study? Cite your study using APA format as
  outlined in the Writing Center.

PSY 325 Week 4 DQ 1 Correlation

•  
• PSY 325 Week 4 DQ 1 Correlation 
• 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? If something else, what? In
  the course of your response, explain why
  correlation alone is rarely sufficient to
  demonstrate cause.

• 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.

  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.

  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?

• PSY 325 Week 5 Final Paper 
• Focus of the 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, suggest alternative
  interpretations of the results. This process will
  allow you to apply the concepts learned in the
  course in the interpretation of actual scientific
  research.
