Discussion "Why Study Statistics?"

Hello Class! For this discussion you can choose which question you respond to. Feel free to respond to both, however only one is required. Please respond to one of the following questions:

Question A

Tell us about yourself so you can meet and greet other fellow Grantham University students within your course. Include what you believe to be your current knowledge level of this course topic and what you hope to learn before the course is over.

Question B

Write a 200 word essay/explanation on why you should study statistics. In your answer define the word statistics and discuss how you will use statistics in your career field.

W2 Ideal Statistician

Business professionals who use statistics are not mere number crunchers who are “good at math.” As Jon Kettenring succinctly said, “Industry needs holistic statisticians who are nimble problem solvers” (www.amstat.org).

Consider the criteria listed below:

The ideal statistician

Is technically current (e.g., software-wise)

Communicates well

Is proactive

Has a broad outlook

Is flexible

Focuses on the main problem

Meets deadlines

Knows his/her limitations and is willing to ask for help

Can deal with imperfect information

Has professional integrity

Locate an individual in your company who exemplifies these characteristics and interview them on the importance of understanding statistics and the challenges they may face with data. Ask them how they demonstrate these characteristics in their job.

You may summarize your interview in a brief narrative (250-500 words) or you may audio/video record the interview and upload it for viewing to the discussion forum.

W3 Discussion "Deceptive Statistics"

There are examples of deceptive statistics everywhere - visual data presentations (charts/graphs)—from magazines to newspaper articles. Locate a particularly outrageous chart/graph and interview people in your company about the message they interpret from this example. Ask them the purpose of the statistics/research--chart/graph, the strengths and weaknesses of the chart/graph and if are they convinced or suspicious of its findings. What would they recommend to make the results more credible (if anything). Make an audio or video clip of your interview and upload it to this cite. Be sure to include a picture of the graph in the discussion forum.

W4 Statistics Pitfalls

As a person who understands and uses statistics to solve problems in business you know that you must use the right statistical tool to compare data against theories. If the data doesn’t support the theory under investigation, you either reject or revise your theory. (You don’t revise the data!)

However, you understand that pitfalls may exist in the data collection process and the reasoning process. For instance, you know to watch for:

1.      Making conclusions about a large population from a small sample.

2.      Making conclusions from nonrandom samples

3.      Attaching importance to rare observations

4.      Using poor survey methods

Working with someone in class or in your company…explain/discuss each pitfall and how it might impact good problem solving in the business environment. You may write a short narrative of 250-500 words or you may create an audio/video file to be viewed by members of the class.

You must read, listen or view 2 other students presentations and in your response—indicate how their answers are the same or different from yours.

W5 Classical Hypothesis Test

Discuss the “Classical Hypothesis Test: A Five-Step Procedure” on page 173 of your textbook.

1.      Write the 5 step procedure

2.      Explain the importance of checking for normality in the assumptions in step 2.

3.      Why is step 3 so difficult for most statistics students?

4.      How do you select the correct test statistic?

5.      Can you ever “prove” the alternative hypothesis?

W6 Necessity of Good Writing Skills

Statistics utilizes math and science in its application. So, why do you need to be an effective writer when using statistics?

Working with someone in class or in your company…explain/discuss why you need to be a good writer when problem solving using statistics.

You may write a short narrative of 250-500 words or you may create an audio/video file to be viewed by members of the class.

You must read, listen or view 2 other students presentations and in your response—indicate how their answers are the same or different from yours.

W 7 Ethical Guidelines

Go to the website www.amstat.org. Discuss the ethical guidelines that have been extensively reviewed by the statistics profession.

Why are safeguards in plact to protect professional integrity but also to minimize ethical breaches. Why do analysis need to know and follow accepted procedures, maintain data integrity, carry out accurate calculations, report procedures faithfully, and proftect confidential information?

You may work with a classmate or a person at your place of work to discuss the importance of these questions.

You may write a short narrative of 250-500 words or you may create an audio/video file to be viewed by members of the class.

You must read, listen or view 2 other students presentations and in your response—indicate how their answers are the same or different from yours.

W8 Reflection

Review and reflect on what you learned in the past 8 weeks. What is the most practical and easily applied lesson you learned? What was the hardest to grasp? Why?
