Is there any difference in statistics

  1. Read chapters XI, and XII, and XIII in the online textbook. Watch the videos and powerpoints that go with each chapter.
  2. Examine the NCbirths database (attached here). Pick three of the following research questions:
    1. Is there a relationship between a mother’s age and the birth weight of her child?
    2. Is there a relationship between whether a mother smokes or not and the birth weight of her child?
    3. Is the birthweight of babies from white moms different than those from nonwhite moms?
    4. Is there a relationship between the mother’s weight gain during pregnancy and the birth weight of her child?
    5. Is there a relationship between the mother’s marital status and the birth weight of her child?
    6. Is there a relationship between the mother’s age and her marital status?
    7. Is there a relationship between the father’s age and the mother’s marital status?
  3. Find two published articles dealing with each of your selected questions. Write a one-paragraph summary of what each article says about your research question.
  4. Determine the mean, median, mode, standard deviation, and variance as applicable for the variables involved in your study. Provide a graphical analysis for the variables that cannot have numerical statistics calculated.
  5. Determine the type of test you will use for each of your research questions and the null and alternative hypothesis for each question.
  6. Conduct the appropriate statistical tests at the .05 significance level.
  7. Write a short report ( 1 to 2 pages for each research question) that includes the results of your analysis. Present the results and discuss the implications of your findings. Include whatever graphs or statistical output you may have generated in answering these questions along with a short explanation of your analysis. Are your results consistent with the published research on the topic? Why or why not?

VIDEO WEEK 2

 Prior to beginning work on this discussion forum, read Chapters 3 and 4 of your textbook. Design a study that has a false correlation caused by lurking variable. Watch this week’s video for an example study, and to learn more information about this concept. 

 Dr. Kevin Kuznia, Academic Department Chair. 

TRANSCRIPT OF VIDEO

]In your discussion this week, you’ll dive into the concept of correlation, causation, and lurking variables. Todemonstrate this, I performed this fascinating study over the summer where I learned that taller people are betterat math than short people. I know you may not believe me, but it’s true. Let me prove it to you.By the end of this video, I will have you convinced that our results are accurate. What are the various aspects ofmath that people need to understand? For an example, counting, addition, subtraction, fractions, decimals, andfinally, geometry and algebra. We can all agree that this is the progression of mathematical ability for the averagestudent.On our y-axis, we’ll plot heights. How much mathematical ability does a person have when they are 1 foot tall?None, they’re a baby. When a person’s 2 feet tall, they can probably count to 10. A person who’s 3 feet tall shouldbe able to add and subtract. At 4 feet tall, they should be able to perform fractions and decimals. At 5 feet tall,they should be able to complete algebra and geometry problems.Looking at our chart, the data clearly shows that people who are taller are better at math. But what’s the problemwith my study? Age. Age was never mentioned in my study. By leaving out age, I’m leaving out a confounding orlurking variable.While this is a simple example, this happens often in real life studies. This is why we need to check the reliability ofour studies and consider any lurking variables that may not have been considered when conducting the study.In this week’s discussion, you will design a similar study that has a false correlation caused by other variables.Your classmates will need to try to correctly identify the lurking variable in your study.[MUSIC PLAYING]

In this paper, you will make an arguable claim that is supported by credible evidence.  A sound argument is different from an opinion. An opinion is a belief that lacks a basis in logic or factual evidence. Instead, for this paper, you will use the writing process to form a position on your chosen topic, an argument that is based on logic and factual evidence found through research. So, instead of starting with an opinion and finding sources, you start with sources and use them to form a position. 

An argumentative essay asks you to take a stand on an issue, support it with persuasion, reasons, and evidence, and to address the opposition’s position.  To accomplish this goal, you will research and investigate your topic by building a source list that represents credible, scholarly, authoritative voices.  You must responsibly integrate and discuss these perspectives into your writing, demonstrating how they either support or go against your own argument.  All claims should be backed up by sources, whether quoted directly, summarized, or paraphrased. 

Organization Tips: Begin with an introduction that builds readers’ interest in the topic and ends with a concise thesis statement that makes an arguable claim about a problem. This is the foundation on which you will build your argument.

The subsequent paragraphs should give evidence from scholarly sources that prove the claim. Those body paragraphs should include a topic sentence that encompasses a single aspect of your argument that you will write about in that paragraph only. Remember, paragraphs are like containers, and each container can only hold one subtopic. Each paragraph’s topic sentence needs to be backed up with evidence and be tied back to the thesis. You must also acknowledge oppositional points by incorporating and refuting counterarguments.

Don’t forget a conclusion that summarizes the argument, emphasizes its importance, makes a call to action, and/or looks to future implications. No new information should be introduced in the conclusion.

The approach to this can be in a style you find makes sense for your subject, such as an Introduction > Problem > Cause > Solution > Conclusion approach, or any other pattern that logically outlines your argument. There are handouts to guide your set-up here download.

IMPORTANT POINT: The topic you choose for this paper will be your topic for the entire class, meaning it will also be your topic for the qualitative research paper and the commentary article.  Keep in mind, the qualitative research paper requires you to interview an expert (academic, professional, or someone closely related to the topic).  As you choose your topic, be sure that you will be able to interview an expert in the field or with background experience related to the topic. 

Paper requirements:

  • Be a minimum of 1000 words, but no more than 1500 (not including the Reference page).
  • Use at least 4-5 reputable (Links to an external site.) sources
  • Be in APA format (Title Page, Paper, References)
  • 1-inch margins
  • Double-spaced, Times New Roman, 12-point font
  • Indented paragraphs
  • Third person POV (no I, you, we, us, our)
  • No contractions

Strategic Marketing: Review Questions

 

Part 1: Review Questions

  1. Forecasts have powerful influence on what companies do, through budgets and other planning procedures. Thus, forecasting merits significant management attention and commitment. Provide an example of a budget or sales forecast for a major airline and outline the components of this budget or forecast. 
  2. Superior market knowledge is not only an important source of competitive advantage, but it also results in happier, higher volume of, and more loyal customers. Do you agree or disagree with this statement? Why or why not? Defend your answer.
  3. Much can go wrong in marketing research and often does. Becoming an informed and critical user of marketing research is an essential skill for anyone who seeks to contribute to strategic decision making. Do you agree or disagree with this statement? Why or why not? Defend your answer.
  4. Why do market segmentation and target marketing make sense? Provide an example for the airlines industry. 

Part 2: Sales Forecasting in the Airlines Industry

As a marketing manager for a major airline, you are faced with strategic planning decisions of growing sales and increasing market share in the leisure travel market. Your boss walks into your office and requests an analysis of past sales in the leisure travel market using regression analysis (Tip: Review video Forecasting in Excel Using Simple Linear Regression in Activity 4.2). Using the Excel data file linked below, create a regression analysis with a graph that you can present to your boss for a meeting next week. Include a summary of your findings that:

  1. Determine if sales are increasing, decreasing, or staying constant based upon the regression forecast. 
  2. Explain the deviations in sales demand. 
  3. Provide your boss with a suggested strategic directive based upon your findings.

Impact of Politics

Prior to beginning work on this assignment,

Read Chapters 5 and 6 of Macroeconomics: Private and Public Choice.

Read Chapter 3 of Popular Economics, What the Rolling Stones, Downton Abbey, and LeBron James can Teach you About Economics.

Listen to Steve Forbes’ insights on this topic by viewing the video Can the Government Run the Economy? (Links to an external site.)

Watch the Q&A with Steve Forbes (Links to an external site.) video available in the window above.

Research and review credible sources to gain an understanding of the pros and cons of government intervention.

The role of government in the economy is often debated by economists and business people. The debate ranges from having little to no government intervention to having a strong government presence in both business and social settings.

Thinking through the pros and cons of government intervention, research and identify two government agencies, departments, or regulations where the government is heavily involved in the economy that you agree is helpful and necessary. Then, research and identify two government agencies, departments, or regulations where the government is involved in the economy that you disagree with and believe the free market would be better. Be specific in your selected government agencies, departments, or regulations. It may be possible to use the same government agency, department, or regulation for both sides. For example, the Environmental Protection Agency (EPA) may have regulations or interventions that you both agree and disagree with. Since EPA is used here as an example, do not use it in your assignment.

For each selected example (four total),

Assess the government intervention providing both the pros and cons.

Discuss whether you agree with the government intervention providing facts and support for your opinion.

Thoroughly explain and support your rationale.

Critique the influence of the political process (for example, lobbying) on each of your examples.

The Role of Government and the Impact of Politics paper

Must be three to four double-spaced pages in length (not including title and references pages) and formatted according to APA Style (Links to an external site.) as outlined in the Writing Center’s APA Formatting for Microsoft Word (Links to an external site.) resource.

respondo eito

Please respond to the following :

 The purpose of this discussion is to analyze the definition and cause of fatigue as well as explain how thyroid function impacts this symptom. Fatigue can be acute or chronic; it is often described as weariness not relieved by rest, affecting energy, motivation and concentration (“Fatigue definition,” 2020). Other coinciding symptoms involve stress, anxiety, irritability and muscle weakness. There are many causes of fatigue since it is a general symptom; differentials to consider are excessive stress, sleep disorders (such as insomnia and sleep apnea), altered thyroid function and respiratory conditions (such as COPD) (“Fatigue,” 2020). More specifically, stress and sleep disorders go together. When a person faces excessive stress from life events, such as death or loss of a job, they can be irritable, depressed, and hopeless for a long period of time. This constant state of arousal can lead to sleeping trouble, ultimately causing a sleep disorder. The mix of these two conditions can cause fatigue (Browne, 2018). In addition, the thyroid impacts fatigue because this structure is responsible for metabolism. With too much thyroid hormone, the body goes into overdrive. When there is too little hormone, the body slows down. Organs involved in thyroid function include the brain, liver, kidneys, bones, and skin. Fatigue is mostly impacted by hypothyroidism because there is a slowing of body systems causing not only fatigue, but also constipation, dry skin, and brittle nails and skin (“The lowdown on thyroid slowdown,” 2018). Hence, fatigue is a general symptom caused by several different conditions.

Requesting a Letter of Recommendation 

Many schools, internships, or jobs will require you to present letters of recommendation from former professors, employers, or non-relatives who can be character references. To obtain a letter of recommendation, you need to know how to ask for one, professionally.

1. Choose an appropriate person. Before you choose which person to ask for a recommendation, ask yourself:

· Does this person know my name and something about me?

· Have I ever spoken to this professor outside of class or employer outside of work?

· Did this professor give me a grade of ‘B’ or higher in the course? Did this employer ever recommend me for a promotion or commend my work?

· Have I kept in touch with this person since leaving their class/place of employment?

2. Put “Recommendation for [your name]?” as the subject line.

3. Address the letter properly. Even in an e-mail, you want it to look nice. If you were on a first name basis (meaning they specifically asked you to call them by their first name and you did so constantly) address it by their first name. Otherwise use their appropriate title. Let’s pretend we’re writing a letter to Dr. Jones who was your professor for Archaeology. Dr. Jones was not on a first name basis with you, so you will start the letter with, “Dear Dr. Jones” followed by a comma or a colon. Make sure you spell their name right!

4. Start the first paragraph by stating what you want: “I am writing to ask if you would be willing to write a letter of recommendation for me.” Do not keep him or her guessing. In the next few sentences, lay out the facts:

· Your name

· Year in school/Major

· Which course or courses you took with this professor, when, and what grade you earned, OR what you did for this person while working with them

· Why you need a recommendation [that is, what you are applying for]

· When the recommendation letter is due

5. Outline your relationship with this person in the following paragraph and point out why you have asked him or her specifically. Tell a little about yourself and why you are interested in the scholarship, graduate program, or job for which you need the reference. You should also attach your resume, if you have one.

6. Use the third paragraph as an opportunity to hint at what you’d like the professor to say about you: You’ll want to include any information about yourself which they may not be aware of. Some subtle ways of letting them know are:

· “I believe that you’re aware through our conversations and my participation in your course that I’m dedicated to the field of archeology. I’ve completed my degree in Archeology as of June of this year. I also have extensive experience in cataloging items gained through my internship.”

· “My other references will be able to talk about my academic ability, but you are the only one who really knows how hard I worked outside of classes and some of the obstacles I faced. I was hoping maybe you could talk about how I handle stress and deal with setbacks, because those are qualities the selection committee wants to see.”

7. Give them the details. Where does the letter need to go? And when do you need it? You’re already asking them to put themselves out and write the letter for you. Don’t ask them to address it and put postage on it for you, too. You want to be the LEAST amount of trouble, so they are not annoyed by having to do work you could have done for them (and should have). Plus, this way you can assure yourself that it was sent. If they offer to mail it for you, let them. If they’re always forgetting to do things like put items in the mail or grade exams, then tell them that you need or want to present it in person with other letters, or other materials. That way you can be sure you have it. But include this in the e-mail so they know the time frame.

8. Close with information about how you will follow-up: “I’ll drop off the form and a stamped, addressed envelope in your faculty mailbox this week. I’ll also send you an email reminder a week before the recommendation is due.” Or, “I need to submit the letter of recommendation by August 3rd. If you’re willing to write me a recommendation letter, please let me know and I’d be happy to come by any time to pick it up.”

9. Thank them, whether or not they write the letter. “Thank you in advance for your time, and consideration. I also wanted to extend an additional thank you for the time I spent under your instruction. I really enjoyed your course, and I can’t express how much I’ve taken away from Archeology 101.” If they were truly that special teacher, you can be more effusive in your praise. “I know I’ll take the things I’ve learned in that course, and apply them in my life’s work. Your mentoring really had a positive impact in my life, and I can never thank you enough.” Offer to write the recommendation letter yourself and have them sign it. This way, it saves them time and effort so they will be more willing to do it, and you will be able to include any content you want.

Other things to remember about requesting a Letter of Recommendation:

Prepare to send your email request at least 5-6 weeks before the date by which the recommendation must be received. Don’t wait until the last minute to ask them. They lead busy lives, and you don’t want them to rush through your recommendation, if they can even make the time to write it.

Follow through as promised by delivering necessary materials and sending a reminder. Follow up the e-mail with a phone call if you haven’t heard anything in a week, two at the most. If you need to call, don’t assume anything. First, see if they’ve even seen your e-mail. If not, be prepared to do your request verbally.

Before the deadline, take responsibility for checking with the scholarship program, graduate school, or prospective employer to verify that the recommendation was received. If not, send a brief, polite email to the professor and offer to pay for overnight delivery.

Thank them again. After you get your letter of recommendation, send a thank you note to the professor. If the recommendation is in the right hands, send the professor a hand-written thank you note via U.S. mail, not via email. It’s not only polite and the right thing to do, but you never know when that will pay benefits down the road. You may need another letter at another time, or if you’re in a similar field, they may be able to assist you at some other time. If the letter does the trick and gets you the position, call the professor to share the good news!

Building a Health History

Effective communication is vital to constructing an accurate and detailed patient history. A patient’s health or illness is influenced by many factors, including age, gender, ethnicity, and environmental setting. As an advanced practice nurse, you must be aware of these factors and tailor your communication techniques accordingly. Doing so will not only help you establish rapport with your patients, but it will also enable you to more effectively gather the information needed to assess your patients’ health risks.

  • How would your communication and interview techniques for building a health history differ with each patient?
  • How might you target your questions for building a health history based on the patient’s social determinants of health?
  • What risk assessment instruments would be appropriate to use with each patient, or what questions would you ask each patient to assess his or her health risks?
  • Identify any potential health-related risks based upon the patient’s age, gender, ethnicity, or environmental setting that should be taken into consideration.
  • Select one of the risk assessment instruments presented in Chapter 1 or Chapter 5 of the Seidel’s Guide to Physical Examination text, or another tool with which you are familiar,      related to your selected patient.
  • Develop at least five targeted questions you would ask your selected patient to assess his or her health risks and begin building a health history.

Post a summary of the interview and a description of the communication techniques you would use with your assigned patient. Explain why you would use these techniques. Identify the risk assessment instrument you selected, and justify why it would be applicable to the selected patient. Provide at least five targeted questions you would ask the patient
