Although you have now completed the course, one additional action is a good practice at the conclusion of every online course. Take the time to consider what you accomplished or struggled to accomplish.

Reflect on the major concepts you studied in this course:

  • Frequencies, percentages, and normal curves.
  • Descriptive statistics (mean, median, mode, graphical displays, et cetera).
  • Inferential statistics (t tests, ANOVA, correlation, chi-square test, et cetera).
  • Hypothesis construction.
  • SPSS use.
  • Application of statistics to real-world information.

INSTRUCTIONS

Create a post of approximately 500–600 words that addresses the following reflective questions about the concepts covered in this course:

  • Relate each concept to how it has improved your professional and personal understanding of statistics and measurement in the workplace or in your community.
  • Indicate in detail how you have applied one course concept in a workplace or personal situation.
  • Discuss in detail, with the use of an example, your most valuable lessons learned in this course.
  • Discuss the suggestions you would give other learners to ensure a better online educational experience, based on your own experiences in this course.

statistic paper

there is the statistic paper. please finish the research paper as following the documents.

As a reminder follow the Phase 5 outline as provided in the Research Paper Instructions posted to Canvas If none of your coefficients are significant — then for the section that discusses Marginal Effects — be sure to use the word ‘if we assume the coefficient is significant then the marginal effect would be ….’ and then interpret it. Reminder that ME are only calculated on continuous variables and not discrete.
For the prediction section of the paper be sure to use numbers from your data set, the X’s, to predict your Y and then interpret the result.

For those of you who have models where none of the coefficients are statistically significant — you might try running your model again but change the level of significance from .05 – the default value in Excel to .10. In the regression dialogue box you can change the alpha. I don’t know if it will help but it might be worth trying. This is your decision.

reminder : The R-Squared, F-Test, and slope coefficients are not significant in your model, and that is okay.For the paper, you should write about that the r-squared, f-test, and slope coefficients in your model are not statistically significant and why that is bad, but you should also write about what if they WERE statistically significant (even though they are not in the model). You will need to say (let’s assume that the r-squared is statistically significant) and write about the good (higher variance is captured) and bad (possible multicollinearity). the last file is sample paper

let me know if you have any questions.

at least 6 pages ( for content ) , please show your clear ideas for it.

This signature assignment is designed to align with specific program student learning outcome(s) in your program. Program Student Learning Outcomes are broad statements that describe what students should know and be able to do upon completion of their degree. The signature assignments may be graded with an automated rubric that allows the University to collect data that can be aggregated across a location or college/school and used for program improvements.

Assignment Steps

Resources: Tutorial help on Excel® and Word functions can be found on the Microsoft® Office website. There are also additional tutorials via the web that offer support for office products.

Scenario: Wilson Corporation (not real) has a targeted capital structure of 40% long term debt and 60% common stock. The debt is yielding 6% and the corporate tax rate is 35%. The common stock is trading at $50 per share and next year’s dividend is $2.50 per share that is growing by 4% per year.

Prepare a minimum 700-word analysis including the following:

  • Calculate the company’s weighted average cost of capital. Use the dividend discount model. Show calculations in Microsoft® Word.
  • The company’s CEO has stated if the company increases the amount of long term debt so the capital structure will be 60% debt and 40% equity, this will lower its WACC. Explain and defend why you agree or disagree. Report how would you advise the CEO.

BSTA385 Duquesne University Carvalues (Business Statistics)

Attached is assignment and the excel spreadsheet to go with it

A preview of the assignments follows:

  • construct 4 histograms to describe the distributions of Price, Cost/Mile, Road-Test score, and Value Score.
  • obtain the following descriptive statistics for each histogram which includes: mean, standard deviation, sample size and the five-number summary.
  • construct a pie or bar chart to display the distributions of Size and Predicted reliability, labeling the graphs with relative frequencies.

Notes:

– Be sure to clean up the excess descriptive statistics given in ‘data analysis, descriptive statistics’

output by removing anything that is not requested above.

– And reduce the decimal places to 2 or 3 decimals.

– If using data analysis, simply copy and paste the output given and add Q1 and Q3 to the table.

If using Excel functions, create a table and insert or type the requested statistics

Copy and paste each graph and the summary statistics.Please edit the output so that it is readable and fits easily in your report.(15 points)

b.Which histograms appear approximately normally (bell-shaped) distributed and which appear decidedly not bell-shaped?

  • c.Based on your answers from parts a) and b), give a brief summary report describing the characteristics of the typical sedan in terms of Size, Predicted reliability, Price, Cost/Mile, Road-Test score, and Value Score.(10 pts)

** Remember,

  • if the distribution is deemed bell-shaped, you will report the overall min and max, and use the mean and standard deviation to identify the middle 68% (by the Empirical Rule) of cities sampled.
  • if the distribution is NOT deemed bell-shaped, you will report the overall min and max, and use the median and Q1 and Q3 to identify the middle 50% range of cities sampled.

d.Now, separate the Price by size of the sedan.I would suggest that you copy and paste the size variable and the price variable onto a separate excel sheet.Then filter by size carrying the price.Make three separate columns of price, one for each size category; like the example showing the first three sedans in each size below:

Provide key descriptive statistics for describing price by size AND construct a side-by-side boxplot.Copy and paste the key descriptive statistics and a copy of the side-by-side box and whiskers plot for a visual comparison of the price by size of the car.(8 pts)

Based on the separated descriptive statistics provide a brief summary report comparing the price by car size. Does this information suggest that the price of a car is noticeably different for sedan size categories?Explain.(3 pts)

e.Develop a scatterplot and compute the sample correlation coefficient to explore the relationship between cost/mile (on the x-axis) and the value score (on the y-axis). Copy and paste the labeled scatterplot and the correlation coefficient.Use this information to briefly summarize the relationship.(4 pts)

Extra Credit (3 pts):You may compare the household income between those subscribers planning to make a real estate purchase in the next year (or between those that have children or not), like part d. above.Provide the box and whiskers plot comparison and the descriptive statistics.

Multiple regression with dummy variables

In this project, you will learn how to run and interpret an estimated multiple regression model with a dummy variable. You will be given a data set called “Auto MPG Data Set” which you can download in “Table of Contents – Project 3” in sakai. The data set contains 391 samples and seven variables: six continuous variables mpg, cylinders, displayment, horsepower, weight, acceleration and one dummy variable bin year. The dummy variable bin year equals 1 for vehicles with model year before 1976 and 0 for those with model year in or after 1976. The goal of the analysis is to develop a regression model for predicting mpg using the remaining variables. That is, the response variable (y) is mpg and the explanatory variables (x) are cylinders, displayment, horsepower, weight, acceleration, bin year.

Week 4 Grad. School: Choose & Describe due 7/20 by 11:59 p.m. Please include a title for each

assignment. In addition to an introductory paragraph and a conclusion paragraph, one well-

developed, specific, and very clear paragraph must be devoted completely to each of the three areas

listed. In organizing each paragraph, be sure to include a sentence that specifically identifies the

intent of that paragraph. Do not approach writing in this assignment as a “one (or two or even three)

sentence coverage of each topic.” Each of the three areas MUST include well-developed and

thorough content that demonstrates synthesis, analysis, and application.

Note: In choosing a graduate school for this assignment, you must be able to find answers to each

of the required areas that follow. If your “preferred” graduate school doesn’t have that information, you

must select one that does. You also must select a program that specifically requires a version of a

“letter of intent,” purpose, or personal statement essay.

Assignment: Write a “3-5” paper in which you use 5 paragraphs that include an introduction,

conclusion, and a well-developed, specific, and very clear description of the following 3 areas:

I. Do your research! Identify a graduate school and

program within it in which you have an interest in

obtaining a “Masters’ Degree.

If you graduate school does not interest you in the “near future”, consider that at some point you may

change your mind! You will write the paper “as if” therefore.

For example, “back in the day” when I graduated from college with a bachelor’s degree, going on to

get my master’s was the furthest thing from my imagination. I thought I wanted to teach English in

high school, though I had no idea what was or was not required to do so. I didn’t get a full time

teaching job until many years later when I taught at a community college: but I did get hired as a

social worker! I had taken sociology in college but had just one social work class because I didn’t like

the main instructor who I thought was boring. At work, I quickly discovered there were many things I

didn’t know about doing social work–and the first area was in mental health. I contacted people a

great many times in that field in effort to learn more. I was eventually even hired to do that work. I still

didn’t have all the answers of “how to do this”– but I still didn’t consider graduate school. Then one

day the opportunity jumped right into my face and I took it–and though I struggled going to grad.

school full time for two years as I worked full time and had to maintain a family that included a toddler

daughter who scribbled in my textbook, it was one of the best decisions I ever made for my

professional future. Given this assignment as an undergraduate student, I would have struggled and

probably not written it the way I would now. However, I might have learned more about myself and my

commitment to “make a difference” in SOME way! Achieving goals begins with a deep self-

assessment and progresses through an organizing of specific, measurable action steps that direct

you to success in a meaningful plan.

A. Discuss an area in the program in which you would like to specialize, and identify if this program

provides an opportunity for this specialization. If there is no overt opportunity for specialization,

discuss how you would plan to address this.

B. Describe the geographic location and its proximity or distance from your home.

C. Identify contact information including the URL, address, and name of Dean of the school.

D. Describe the research or other “background” interests of at least 3 faculty in the program

E. Identify other Interesting areas to include related to individualizing this program!

Responses 2

II. Describe the requirements for entry into the

program.

A. What specialized testing is required? For example, do they require a GRE or an “MCAT” or an

“LSAT,” etc.?

B. What are the application fees?

C. What is the deadline to apply?

D. How many undergraduate credit hours are required for admission?

E. Identify other requirements and/or related and interesting areas to include related to individualizing

this program!

III. Describe the program’s mission and goals and

how they “match” yours.

A. Describe–in sentences that use italics and underlining for the specific key words or phrases–at

least five key words and phrases the program uses to describe expectations for students. Choose

only those key words that are specific to a program, clear, and unique to their setting. (Don’t forget:

use italics and underline each of the five examples of their key words and phrases.)

B. Discuss how those key words and phrases link directly to your academic and career goals and

objectives. This is a very important section in which it is important to demonstrate strong

critical thinking skills in synthesis, analysis and application!

C. Summarize the content of the program’s letter of intent.

D. Include a summary of your own goals and objectives and what you learned from researching the

graduate program’s goals and objectives.
