Inferential Research and Statistics Project

Part 1

Select one of the following scenarios based on your particular field of interest in psychology:


  • General Psychology:
    • Clinicians at a small clinic have been introduced to a new method to treat post-traumatic stress disorder (PTSD) in their clients for veterans. Research indicates that virtual reality (VR) is a highly effective treatment option for patients with PTSD. Currently, the clinic uses only cognitive processing therapy (CPT) with their patients suffering from PTSD. The clinicians would like to find out whether VR therapy has different results from CPT therapy. The measure used by the clinic to measure PTSD symptoms is the Combat Exposure Scale. Both therapies need to be applied for a minimum of 12 weeks to be effective.


Write a 525- to 750-word paper that addresses the following for your chosen scenario:


  • Clearly define the problem or issue you are addressing. Provide a brief background of any research you have found that might affect your research hypothesis.
  • Create a research hypothesis based on the information provided in each scenario. You have been given a data set (Excel document) with two sets of interval data (just the numbers, as you must decide what they represent, such as method A results or method B results). This means you are going to test one thing against another, such as which method works best (step 1 of the steps to hypothesis testing). State the null and research hypotheses. Explain whether these hypotheses require a one-tailed test or two-tailed test, and explain your rationale.
  • Describe the sample you will use. Sample size will be 30 for each group, which are provided in your data set. Explain what type of sampling you selected.
  • Do you think you would also collect some descriptive data, such as gender, age, or shift? Why do you think it makes sense to collect descriptive data?


Format your paper according to APA guidelines.




You have a hypothesis that two drugs have different effects on lowering anxiety. You would have anxiety scores for drug A and anxiety scores for drug B (all after 4 weeks of treatment) to run inferential analysis for after 4 weeks.


  • Null hypothesis is H0: drug A = drug B
  • Research hypothesis is H1: drug A ≠ drug B
  • Dependent variable: Anxiety score changed after treatment.
  • Independent variable: drug treatment


Because you did not state a direction in your hypotheses (better than or worse than), this will be a two-tailed test. You are looking for differences in either direction. You would set your alpha level of .05 and have a sample for each group of 30 people that were volunteers for the study.



  • Provide the main finding of the study. What did you prove or fail to prove?
  • Provide recommendations based on your findings.


Format any citations in your presentation according to APA guidelines.

ENGR 381 Contemporary Issue Assignment
Review and Reflection on Hydraulic Fracturing
DUE DATE: 15th December
Thermodynamics is fundamentally a subject about energy, which affects our lives in many
different ways. The availability of energy impacts our lifestyle, environment, economy, and
health. One of the primary controversial current topics related to energy is hydraulic fracturing.
Our contemporary issue project this semester will focus on hydraulic fracturing, which is a
controversial technique for harvesting natural gas (and other hydrocarbons) from the earth. This
project has two parts, the first being related to objective aspects of hydraulic fracturing and the
second being subjective to yourself and your own values. The final product of this project will
be a formal written report. The breakdown for the report will be as follows:
1. Part 1: An overview of hydraulic fracturing (or fracking) (2-3 pages, 12 point font, single
a. A technical description of fracking
b. An overview of benefits, potential and realized
c. An overview of drawbacks, potential and realized
d. What biases do you detect?
e. Are there discrepancies in your resources?
2. Part 2: Your view on hydraulic fracturing (1-2 pages, 12 point font, single spacing)
a. Evaluate this technology from your personal perspective
b. Engage your values and beliefs as well as engineering ethics and virtues
c. Being as realistic as you can, what is your final recommendation regarding this
technology? Try to be convincing.
This project will require the gathering of information from a variety of sources. You should
include at least one from each of the following:
1. Documentary films
2. Mainstream newpaper articles
3. Blogs/editorial websites
4. Scientific articles
5. Editorials/articles/position statements from engineering societies (e.g. ASME, AIAA,
ACS, etc.)
6. Business magazines
Look for bias (implicit or explicit), and comment on it in your writing. Cite your research
materials throughout your report. Find your own references; I don’t expect to see the same set of
references for any two reports. Give proper citation to any figures used from your sources. See
the included materials on engineering ethics and virtues, and cite these as you make your
arguments in part 2.
Grading criterion: Quality of writing (including the use of citations) (25%), completeness of
background in part 1 (25%), articulation of your point of view in part 2 including citations to
ethics/virtue references (20%), persuasiveness (15%), effective use of figures (15%).
See attached documents on engineering ethics and virtues.

Answer the following questions using the information provided above.

  1. What problem are amphibians experiencing worldwide? Please explain it as clearly and completely as you can in the space provided (approximately 150 words). Make sure you address broadly what is happening as well as causal factors involved. (max. 2 pts)



  1. What does the “climate-linked epidemic” hypothesis of Pounds et al. (2006) propose (that is, what is hypothesized to be causing the problem)? Summarize it in 1-2 sentences, using your own words. (max. 1 pt)



  1. List two distinct lines of evidence used to support the “climate-linked epidemic” hypothesis in your own words. (This is data that corresponds to one of the predictions of the hypothesis.

max. 2 pts)



  1. What does the “spatio-temporal spread” hypothesis of Lips et al. (2008) propose? Summarize it in 1-2 sentences, using your own words. (max. 1 pt)




  1. List two distinct lines of evidence used to support the “spatio-temporal spread” hypothesis in your own words. (max. 2 pts)



  1. How are these two hypotheses different in terms of their predictions? Contrast the predictions of each hypothesis. Explain in 2-4 sentences, using your own words. (max. 2 pts)




  1. Please list and explain one strength and one weakness of each hypothesis in the chart below. A weakness is something about the hypothesis (an assumption, way something is measured, piece of data, combination of data, or absence of data, etc.) that makes it less convincing. A strength is something that makes it more convincing. (max. 4 pts)


  Weaknesses Strengths
Climate-Linked Epidemic    

































  1. If you were Ms. Torres, and you had to briefly describe to your students why the frogs have disappeared in this forest, and what you think is the most likely explanation, what would you say? Write your explanation as if you are talking to high school students. Be sure to synthesize the information available; your explanation should include an informed evaluation of the evidence. Please explain it as clearly and completely as you can in the space provided (~100-150 words). (max. 2 pts)




Finally, read carefully the following information and answer the last two questions.


In a new study, Cheng et al. (2011) recently described a new genotyping technique —a way to discover the genotype of the sample— by which amphibian museum specimens can be tested for the presence of chytrid fungus through a simple swab. This DNA-based technique uses the polymerase chain reaction (PCR)2 to detect the presence of Bd DNA in the skin of specimens, and can be used for specimens collected up to 50 years ago.

  1. Please read carefully and as many times as needed. How would you use this new tool to help understand the causes of enigmatic amphibian declines knowing that many museums have been collecting specimens from Central and South America for decades? Provide a specific example or scenario of where and for what purpose, you could use this technique. (For example, what would you test for and in what populations? What would you expect to find, and what would it mean?). (max. 3 pts)


  1. Please read carefully and as many times as needed. How might new evidence from using PCR on specimens from several decades ago strengthen or reject the hypotheses above? Describe how new evidence could be used to produce data to strengthen each hypothesis, and what data that would be. Explain. (max. 6 pts) —-PCR is a molecular technique used to amplify specific fragments of DNA. If the chytrid fungus is present on a frog specimen, chytrid DNA fragments will be amplified with the PCR.

The Learning Set dialogue this week will focus on further problematising your individual workplace-based problem, based on the theories and concepts from the week’s readings.

Approach this week’s Learning Set Participation with a full understanding of the operation of judgmental traps and individual biases within a business context. Start with the Bazerman and Moore (2008) and Drummond (2001) texts as they provide an overview as does the article by Hammond, et al. (1998) from Week 1.
The de Bono Group website provides a cognitive method approach to problem solving to avoid judgmental traps. De Bono suggests that decision-makers think about problems, opportunities, and risk in several different ways before making a decision, i.e. exhibiting balanced judgment.

Use your own research into de Bono’s method to further influence your Learning Set Participation this week as you are asked to consider your identified workplace-based problem through the use of two specific “hats” to shed new light on the problematising process. In turn, your Learning Set members will provide additional insight using another of the “hats.”

After completing the readings, engage your Learning Set members by answering the following:

  • Describe a time professionally where you have made a judgemental mistake. In hindsight, what biases or judgemental traps were evident in your mistake? How could you have counteracted the decision error?
  • Re-describe your CAL Project workplace-based problem for other Learning Set members by using two of de Bono’s Six Thinking Hats, first with your Red Hat on, then with your Black Hat. If you could only have either the ‘black hat’ or the ‘red-hat’ in making important decisions in solving this problem, which would you choose and why? How would each particular hat affect the outcome of your problematising endeavours?
  • In your response to a colleague, research de Bono’s other ‘hats’ and provide an additional insight to his or her Red Hat and Black Hat posts through the use of one of the remaining thinking hats.

It is WMU’s ongoing effort to recruit and retain students. President Montgomery asked your help to find ways to attract additional 500 students in 12 months starting 7/1/2018. Since state funding has been shrinking, there is not much money available for this project. There may be many ideas to accomplish this goal, and several of them can be done concurrently. In order to control the scope of this assignment, you will work on only one idea. Keep in mind that your idea should be implementable, with a clear result, and does not use tons of money (unless you have also identified funding sources for your idea).



  1. Project scope statement
  2. Project requirements (business requirements, quality requirements, functional requirements, non-functional requirements, etc.) Clearly list these requirements in sub-sections.
  3. Your idea in detail.
  4. Double-check if your project constraints cover all three aspects of triple constraints.
  5. Assumptions must be reasonable. If they incur extra cost just to implement your project, then your project is not going to be feasible.
  6. Project risks. Make sure major project risks are included.
    Keep in mind that project risks are those issues that may happen during the project life cycle (i.e., there is a probability for a risk to happen). You will be able to manage them before they happen and when they happen. This is the reason for the risk management plan in later chapters.
  7. WBS (see breakdown techniques in KCH11)
    1. Feel free to present your WBS in bullet points or a hierarchical chart.
    2. WBS must have at least three levels of the breakdown below level one.
    3. Double-check if further decomposition is still needed for tasks at lowest level of WBS. Pay attention to the following rules we have discussed in KCH11 when determining if a work package needs a further breakdown:
      1. Do you think the actual work can be clearly defined at this level? If not, break it down further.
      2. Do you think a clear picture of budget can be defined at this level? If not, break it down further.
  • 80-hour rule
  1. Is the duration longer than the reporting period? Let’s assume that we need to report our project progress once a month.
  1. Each WBS item should be numbered.
  2. Pay special attention to the 100% rule. Points will be taken off if the WBS has missing tasks for the scope.
  1. Project schedule in MS Project. Note the following requirements for the schedule.
    1. Before working on this item it is very important to practice the exercises in the CCH book. Chapters 4, 5 and 6 are most related to this item of the assignment, but chapters 1 – 3 are there to get you ready for these later chapters.
    2. Make sure the project plan is complete (resources are assigned, durations are estimated, task dependencies are defined, etc.)
    3. Most students find it very useful to use automatically scheduled tasks for ALL tasks in the project plan. See the textbook or search online for how to set all tasks to be automatically scheduled BEFORE you enter the first task.
    4. There should be some resources that work less than 100% of capacity on your project. Build this into your project plan in MS Project.
    5. Define a resource named John Wilson who works in the morning only (8 a.m. – noon) during the weekdays.
    6. Define a resource named Jane Smith who has multiple off days in her calendar.
    7. Define Joe Johnson who works 10 hours a day Tuesday through Friday, but has Monday off.
    8. There should be cost resources defined and used.
    9. July 4th is a holiday. Make July 5th and July 6th non-working days to give the team a longer holiday.
    10. All resources defined should be assigned to one or more tasks. Some tasks may need multiple resources.
    11. Additional pointers and reading (CCH book):
      1. See p. 85 for how to handle equipment resources.
      2. See p. 61 for more about how task duration can be more accurately measured. Ask yourself what the 8/80 rule is.
    12. Paste a screenshot of project statistics (e.g., duration, start date, end date, cost, etc.) to MS Word. See CCH 1 & 2 for details.


  1. Submit both MS Word and MS Project files to the Dropbox area on e-learning.
