• 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.

• PSY 325 Week 1 DQ 1 Types of Data

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

• 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.

• PSY 325 Week 2 Assignment Article Summary

• PSY 325 Week 2 DQ 1 Graphs

• 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.

• PSY 325 Week 2 DQ 2 Standard Normal Distribution

• 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?

• For each of the three to five quantitative
  research studies selected (from peer-reviewed
  sources that were published within the last five
  years), the outline should include a heading for
  the study and the sub-headings for Introduction,
  Methods, and Results. For example

• PSY 325 Week 3 DQ 1 Choose the Analysis

• PSY 325 Week 3 DQ 2 Repeated Measures

• 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?

• 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.

• PSY 325 Week 4 DQ 1 Correlation

• PSY 325 Week 4 DQ 2 Regression

• 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?

• 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.

  Test

• PSY 325 Week 5 DQ 2 Chi-Square Test of
  Independence

• PSY 325 Week 5 DQ 1 Chi-Square Goodness-of-Fit
  Test
• 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.

• 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 wo

• PSY 325 Week 5 Final Paper

• 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.
