SCIE 211 Lab 4:  Correlation and Causation

Instructions

Introduction

Identifying the extent and type of relationships between variables (or phenomena, events, traits, etc.) is an important aspect of the scientific method.  The term correlation is used to refer a mutual relationship that is thought to exist between any two variables, phenomena, events, etc.  While correlation plays an underlying role in establishing causation (i.e. the events must be related in order for A to cause B), the existence of a relationship between variables is not sufficient to imply causation.

 

Correlation and Causation

 

The process of successfully attributing causation is difficult; the causal chain (or pathway) of events is often not clear. Can we be sure that A causes B, or is it, in fact, the other way around that B causes A? Or, is there a hidden third, extraneous, or confounding factor C that can cause one or the other or both? This hidden or lurking third factor (another variable at play/an alternative explanation) is called the extraneous, spurious, or confounding variable.

There are three criteria for figuring out whether or not there is evidence for causation:

1) There exists a strong and consistent correlation. This means that when the alleged cause A is present, the alleged effect B tends to be present as well.  Also, there should be a plausible explanatory model (that is consistent with the data and fits with other scientific understanding) so we can explain the correlation.

2) There is precedence.  This means that both the time-order and direction have been established.  In other words, to say that A causes B, the cause A must come before effect B —or that B does not happen unless A occurs first.

3) All other confounding factors (lurking, spurious, extraneous, or third variables) or alternative explanations have been ruled out.  Causation can only be established if A has been shown to directly cause B, without any other intervening variables.  This allows us to make predictions in advance, that A will cause B.  This predicative relationship can be seen, for example, in the dose relationship — the larger the dosage, the stronger the response. 

Correlation and Causation

To demonstrate this principle, you will look at the relationship between the diameter of a balloon and lung volumes.

Tidal volume is the volume of air that you move into and out of your lungs each time you breathe normally.  Average tidal volume is roughly 500 mL (Moini, 2020)

The amount of air that can be inspired forcibly beyond tidal volume is called the inspiratory reserve volume (IRV). The average inspiratory reserve volume varies dramatically with sex:  3000 mL in males, 2100 mL in females (Moini, 2020).

The amount of air that can be expelled forcibly beyond tidal volume is called the expiratory reserve volume (ERV).   Just like the inspiratory reserve volume, the expiratory reserve volume also varies dramatically with sex:  1100 mL in males, 800 mL in females (Moini, 2020).

Vital capacity represents the maximum amount of exchangeable air that our lungs can move.  It is the sum of the tidal volume, inspiratory reserve volume, and expiratory reserve volume, or:

Vital capacity (mL) = Tidal volume (mL)   +  IRV (mL)   +  ERV (mL)

In this laboratory, you will use a balloon to measure your tidal volume (volume of air moved in normal breath) and vital capacity (maximum volume of air moved).  You will consider lurking variables/confounding factors that contributed to any deviation from expected values.

Correlation and Causation

Objectives: 

After completing this laboratory, you should be able to:

  • Discuss the danger of confusing correlation with causation.
  • Identify extraneous or confounding factors.
  • Explain how we determine support for causation.
  • Evaluate causal claims.

Materials:

  • 1 Balloon (12 inch)
  • Metric Ruler
  • 1 binder clip (or fingers)
  • Pencil
  • Calculator

Procedure – Part I: Measuring Tidal Volume 

  1. Blow up and deflate the balloon several times to stretch it out.,
  2. Sit down and relax. Inhale normally and then exhale only that of a normal breath into the balloon.,
  3. Immediately twist and clamp the balloon (or pinch with your fingers) so that no air escapes.,
  4. Place the tip of a pencil vertically onto the zero cm mark on the ruler. Place the balloon on its side next to the pencil.  (See figure 1).,
  5. Holding the balloon in position, move your pencil to the other side of the balloon.,
  6. Record the diameter (cm) in the table on the Lab 4 Worksheet. Make sure your recorded value has the correct number of significant figures.,
  7. Repeat the entire process 2 more times.,
  8. Calculate the average balloon diameter for your three trials on the Lab 4 Worksheet ,                                               Figure 1

Procedure – Part II: Measuring Vital Capacity

  1. Use the same balloon as used in Part I.
  2. Inhale as deeply as you can and exhale as much air into the balloon as you can.
  3. Immediately twist and clamp the balloon (or pinch with your fingers) so that no air escapes.
  4. Place the tip of a pencil vertically onto the zero cm mark on the ruler. Place the balloon on its side next to the pencil.  (See figure 1).
  5. Holding the balloon in position, move your pencil to the other side of the balloon.
  6. Record the diameter (cm) in the table on the Lab 4 Worksheet. Make sure your recorded value has the correct number of significant figures.
  7. Repeat the entire process 2 more times.
  8. Calculate the average balloon diameter for your three trials on the Lab 4 Worksheet.

Analysis

  1. Use the graph in Figure 2 (below) to estimate the average diameters of your balloon filled by a normal breath and the balloon filled by a deep breath into cc (cubic centimeters) of lung volume.   Record the values in the table on the Lab 4 Worksheet.
  2. Using the conversion 1 cc = 1 mL, convert the volumes in cc to volumes in mL. Record these values in the table on the Lab 4 Worksheet.  These represent your observed tidal volume and observed vital capacity.
  3. Record the expected values (from pre-lab questions 1 an 2) in the table on the Lab 4 Worksheet.
  4. Calculate and record the % difference. Remember, the % difference is:

Correlation and Causation

% difference   =  |(Observed volume   –    Expected volume)     x    100%

Expected volume

Company Harassment Policy

You are the new HR manager for Java Corp. The company has just lost a sexual harassment lawsuit and damages include back pay, front pay, punitive damages, and attorney’s fees. The plaintiff, Ms. Stapel, was a female manager who had a consensual sexual relationship with her male boss, Mr. Rowe. Both moved up in title and responsibility over the past 5 years. After the relationship ended, Mr. Rowe made several offensive comments to co-workers about Ms. Stapel, without her knowledge. Later, a number of other employees, who reported to Mr. Rowe, made offensive sexual comments directly to Ms. Stapel.

Company Harassment Policy

 

The company has a harassment policy but only referred someone who felt harassed to their immediate supervisor and provided no other avenues of complaint. Your first project for Java Corp is to create a formal policy that will protect the employees, the organization, and all stakeholders. You will also prepare a PowerPoint presentation that could be used as a training tool for new employees on the importance of following anti-harassment policies.

Company Harassment Policy

Based on your research of sexual harassment and other forms of unlawful workplace harassment, complete the following:

In a word document, develop an anti-harassment workplace policy that includes the following components:

Objective.

Prohibited conduct under this policy, including discrimination, harassment, sexual harassment, and retaliation.

Confidentiality.

Complaint procedure.

Employee acknowledgment of policy.

Prepare a PowerPoint Presentation for upper management training. In your presentation:,

Explain the legal basis for protecting employees from harassment with supporting laws or regulations.,

Describe different types of sexual harassment found in the workplace.,

This can include but not limited to, quid pro quo and hostile work environment.,

Explain other types of harassment outside of sexual harassment to consider in a workplace policy.,

Articulate how an organization can be at risk of harassment claims and how they can best legally protect themselves.,

Summarize reporting and investigation procedures.,

Company Harassment Policy

Specifically, discuss how the issue or complaint is brought to HR’s attention, who is involved in the investigation, how the communication process works with those involved.

Summarize how the anti-harassment policy should be communicated to employees.

Analyze organizational benefits realized because of having a sound anti-harassment policy in place.

Consider company reputation, employee morale, retention, productivity, and the like.

Additional Requirements

Policy

This part of your assessment should also meet the following requirements:

Length 3 pages Strive to be as detailed as possible in addressing each of the policy’s components above.

Written communication: Communicate in a manner that is scholarly and professional. Your writing should be:

Concise and logically organized.

Free of errors in grammar and mechanics.

Resources: If you use a source in the text of your policy, you need to reference it. The last page of your policy should be your reference list. Format all citations and references in accordance with current APA guidelines.

PowerPoint Presentation

This part of your assessment should also meet the following requirements:

Audience: Create a presentation suitable for the upper management of your selected organization.

Length: 8–12 slides, including speaker’s notes and title and references slides.

Validation and support: Use a minimum of seven relevant and credible scholarly or professional resources such as the Wall Street Journal to support your work.

APA format: Format all citations and references in accordance with current APA guidelines. Refer to the Evidence and APA Campus page for guidance.

Company Harassment Policy

Complexity: Do not get hung up on adding too many graphics, audio, or video. Select a PowerPoint template appropriate for a professional presentation. Please make sure the background color you choose does not interfere with the font selection and that it is easy to read. Do not overbuild your slides; information that supports and expands on what you say should appear as speaker’s or presenter’s notes.

Note: It is expected that your SafeAssign results for the policy document in Word will have a high percentage match, as you are aligning with legal standards. Your PowerPoint presentation should not be nearly as high. Please make sure you cite your sources within both documents according to current APA style.

Your PowerPoint presentation should be saved as a PDF to properly capture the presenter notes.

Secondary  Research Project

The goal of this project is for you to take the problem/issue/question from your intended field that you worked with in Project 2, and use it to develop an academic literature review and proposal of the genre this literature review is MEANT for (i.e. this literature review would go into a grant application, or a study proposal, or an IRB application, etc.).Literature reviews are a particular genre that helps researchers across disciplines position their work within larger scholarly conversations, so that readers can understand the relevance of a project or argument.

 

Secondary  Research Project

Often composed as parts of larger projects (to frame research proposals, as an overview of best practices, as part of a longer publication or as a standalone meta-review), writers use literature reviews to synthesize information, compare and contrast ideas, and clearly describe relationships between well-cited texts to present their own work accurately and persuasively in the context of the scholarly conversation. Ito draw on some of those methods to conduct your research for this .The skill of writing this common scholarly genre is one that will be of use to writers in nearly all disciplines. We will engage with focused analysis of this genre to develop familiarity with the specific writerly moves needed to compose it with confidence.

Learning Objectives

  • Conduct secondary research to investigate a research question, problem or issue in a profession, field, or discourse community (RESEARCH).
  • Analyze the genre of the literature review from the student’s discipline or profession to understand the ways professionals in the field engage with and rhetorical conventions they use to communicate their research and findings (READ).
  • Use a flexible writing process and varied technologies to compose a scholarly literature review that attends to the expected organization, format, and style of the assignment ().
  • Use reflective writing to describe developing knowledge about writing (especially writing in one’s discipline or profession) and about oneself as a writer (including one’s ability to plan, monitor, and evaluate one’s writing process and texts) (REFLECT).

Secondary  Research Project

Task

????For this , you will continue your work with the research problem/issue/question you’ve been working with in Projects 1 and 2.  For most, you will begin by presenting a brief introduction of the major historical developments contributing to this topic in your field, and then spend the rest of the Literature Review mapping out the contemporary work being done on the topic. Alternative approaches are certainly valid but should be decided in consultation with your instructor.By the time you begin working on drafting your literature review, you will have already done most of the significant work required for this project. You will have identified and revised research questions, identified key texts, created a working bibliography, and organized notes to help you synthesize sources and identify gaps, questions, problems, or tensions in the scholarly conversation.To develop a revised, literature review , we will continue to move through several smaller, yet still formal scaffolding steps:

Secondary  Research Project

  • Developing a detailed genre analysis of literature reviews
  • Examining syntax and transitions at a sentence level
  • Submitting a draft for peer review, and
  • Using that peer and teacher feedback to work through – and sentence-level revision and to craft the literature review for a specific audience and purpose.

In your literature review, you will follow the standard genre conventions uncovered during our early analyses. At minimum, your review should include a discussion of the central topic you are investigating and at least two sub-topics that help you focus your research, but it can have more.As implied above, we will review examples of published literature reviews to analyze how writers organize discussions of a major topic and then help readers navigate through a set of related sub-topics. We will also discuss how to frame sources such that readers understand the “broader conversation” about these topics and sub-topics, and how to establish a “scholarly niche” for yourself–a corner of the conversation you would be interested in entering as a professional.

Secondary  Research Project

Reflective Memo

“I suppose I think this reflection is so important because without it, we live the stories others have scripted for us: in a most unreflective, unhealthy way. And I think the stories we make-whether inside the classroom or out, whether externalized or not-construct us, one by one by one. Cumulatively. So I think it’s important to tell lots of stories where we get to construct many selves for us to attempt, some we continue to inhabit.”Kathleen Yancey, Reflection in the Writing Classroom, p. 53Your final  for this project must also include a 350- to 500-word reflective memo addressed to either yourself or your instructor. This memo will tell the story of your learning and writing during this project. Please address the following prompts in your reflection:

  • What were your personal goals for the project? How would you rate your progress toward those goals?
  • How would you rate your progress toward achieving the project’s learning outcomes (listed below)?
  • Tell your story of learning in this project. Relate one or more key moments from class, from your independent work, or from communicating with peers or the instructor. How has your work on this project connected with what you already knew/know? Is this what you expected to learn? Why or why not? What else do you need to learn? How will you go about learning it?

Secondary  Research Project

Evaluation

????

  • Write an introduction that includes brief context and a mapping statement for this literature review.,
  • Integrate discussion of a minimum of 8 scholarly sources relevant to your research question.,
  • Write body  (as many as needed) synthesizing the secondary sources you’ve located and evaluated for this project,
  • Write a paragraph or two in which you indicate/propose a specific academic genre where you might plan for this literature review to go as well as providing a rationale for why this proposed genre would be a good fit for your project.,
  • Cite your sources, both throughout the project and in a works cited or references section using the citation conventions appropriate to your field (I.e. MLA APA Chicago etc.),
  • Design and format your project for accessibility. Use section (H1) and (if necessary) subsection (H2) headers to organize your content.,
  • Revise and edit your writing preparing a clear final draft (2500-3000 words) for submission.,
  • Reflect on your research and writing process and learning and compose your post-project reflective memo following the guidelines for that task., Submit your memo to Canvas along with your final version of your project
