Project #84746 - Data Presentations

There are 2 parts to this assignment and general discussion and then a paper.

 

Part 1:

All that is needed is two or three paragraphs and any references.  The chapter 2 and 3 are referenced from the book Anderson, D.R., Sweeney, D.J., Williams, T.A., Camm, J.D., & Cochrane, J.J. (2015). Essentials of statistics forbusiness and economics (7th ed.). Mason, OH: South-Western Cengage Learning. ISBN: 9781133629658

 

Select a type of graph discussed in the book and give a real-world example of when this graph would be useful to you in a professional application or in your everyday life. You do not need to create the graph. You should only explain why the type of graph you have selected is the best for your example.

 

Part 2:

For part 2 I need an actual paper writtend with references (details below).

 

The status of counties is important. There are more than 3,000 US counties. The median household income (in dollars), average years of schooling, average lifespan (in years), and average number of people per household of 100 chosen counties are provided.

Data collected for a sample of 100 counties in 20XX are contained in the file named Counties, linked at the bottom of the page. Use all 100 data points.

Managerial Report
Prepare a report (see below) using the numerical methods of descriptive statistics presented in this module to learn how each of the variables contributes to the success of a county. Be sure to include the following three (3) items in your report.

  1. Descriptive statistics (mean, median, range, and standard deviation) for each of the four variables along with an explanation of what the descriptive statistics tell us about the counties.
  2. Use the z-score to determine which counties, if any, should be considered outliers in each of the four variables. If there are any outliers in any category, please list them and state for which category they are an outlier. Describe which method you used to make your determination.
  3. Descriptive statistics (correlation coefficient) showing the relationship between median household income (in dollars), and each of the other three variables. Thus, that makes a total of three correlation coefficients. Evaluate the relationships between median household income (in dollars) and each of the other three variables. Use tables, charts, graphs, or visual dashboards to support your conclusions. 

Write a report that adheres to the Written Assignment Requirements under the heading “Expectations for Written Assignments” found in the Guide to Writing and APA Requirements.  As with all written assignments, you should have in-text citations and a reference page. An example paper is provided in the MTH410 Guide to Writing with Statisticslinked at the bottom of the page.

Your report must contain the following:

  • A title page in APA style.
  • An introduction that summarizes the problem.
  • The body of the paper should answer the questions posed in the problem by communicating the results of your analysis. Include results of calculations, as well as charts and graphs, where appropriate.
  • A conclusion paragraph that addresses your findings and what you have determined from the data and your analysis. 

Submit your Excel file in addition to your report.
