Assignment 1
Tip: Read through this document in its entirety before you begin.
The assignment is to conduct research based on the information below, using R. After analyzing the data in R,
document the research and findings in a research paper in APA 7 format. Ask questions if you need to!
Topic: The Center for Disease Control and Prevention (CDC) uses the social vulnerability index (SVI)
to evaluate the impact of disasters on communities, weighting the damage with social factors in
the states of Kansas and Maryland (CDC, 2018a; CDC 2018b).
Problem: Each community requires independent evaluation to identify the vulnerability of the area. Two of
the contributing factors for this analysis are minority status and language limitations. The data
may lack credibility due to the fear of reprisal for persons that fall into these categories.
Exploring the social and physical characteristics, excluding these metrics can provide insight on
the overall impact on the SVI.
Question 1: What impact does the exclusion of the metrics that represent minorities and language limited
individuals have on the predictability of the CDC’s SVI, based on the 2018 data (CDC, 2018a;
CDC, 2018b)?
Question 2: Does the CDC’s SVI have key characteristics that impact the preclude potential exclusion
without limiting the overall predictability of the SVI, based on the 2018 data (CDC, 2018a; CDC,
2018b)?

▪ Mobile homes
▪ Homes with more residents than a home is designed for
▪ Homes with no vehicle
▪ Group quarters or institutionalized quarters
Note: Do not use the columns that are follow-on calculations of
these columns. Variable names
preceded with “E_” are actual measures, while “M_” represents
the margin of error estimates. Do
not include the margin of error estimates at this time.
Considering the research questions, after
subsetting and excluding the variable that houses the STATE
5. field, there will be 13 columns with
relevant information for analysis. The state field can be utilized
in data exploration.
Data Cleaning:
• Only clean the elements of the data that are inaccurately
represented, such as missing values and data
types.
• Do not remove missing values during cleaning. If missing
values need to be removed for analysis
method, do it during the preparation for analysis.
• When changing data values or types, ensure that you validate
that the change occurred and the
change is what was expected.
Analyze:
• Conduct two types of analysis: exploratory data analysis and a
random forest model. You will move
through the sub-stages of Analyze two times; profile, prepare,
and apply is required for each method of
analysis in your program. It is consolidated in your research
paper. Make sure that your analyses align
with the research questions.**
• During exploratory data analysis, exclude visualizations in
6. your final program or research paper that do
not serve a purpose toward the objective of the research or
represent meaningful information. Just
remember, the relationships that do not exist in the data are
sometimes as significant as the
relationships that do exist.
• Profile
o Define your plan for all analyses.
o Your plan for the random forest model will include splitting
the data after seeding it so that
training and testing evaluations can be conducted; additionally,
you will exclude missing values
from the model.
• Prepare
o Carry out actions on the data that are necessary to prepare the
data for the analyses.
• Apply (or Analyze)
o When carrying out the random forest modeling, it may be
imperative to understand how much
time your analyses may take.
o Ensure that you analyze the results and understand what the
different outcomes of the model
7. represent. Provide interpretations of the overall model that is
trained, how the trained model
performs with the test data, and what features are most
important for the explained variance.
Results, Impact of the Results:
• Ensure that all analyses, visual or otherwise included in the
final version of the program, include
interpretations of what these analyses indicate.
• Make sure that you do not speculate! Use evidence to support
any assertions that you make.
Future Recommendations:
• You must also include recommendations for future analysis.
An example might look something like this:
o An opportunity for further research, based on gaps found in
the random forest modeling, is to
look at the ability to tune the parameters further, to improve the
outcome.

o Additionally, an opportunity for future research is exploration
modeling to determine what other
variables, when eliminated, have little or no impact on the
8. ability to predict the SVI based on the
supporting characteristics in the data.
• You will base your recommendations on your findings in the
analysis you conduct.
Bonus challenge:
Create a random forest model for each state you were assigned.
Is there a difference in the models’ results?
What does that result mean in terms of the data? Make sure that
you do not speculate! Use evidence to
support any assertions that you make.
Required files to submit:
1) Research paper in APA 7 format; MS Word document file
type
2) R Script; final version
Good to know:
• When submitting in Blackboard, you may receive an error,
because the R file type is not recognized.
That is okay. It is only indicating that SafeAssign cannot
evaluate that part of your submission.
o The research paper will be written in a professional writing
9. style, following APA 7 student paper
format; you can use the student paper template.
o The document shall be 3-5 pages or at least 800 words. The
page count does include the cover
page or reference page.
o Ensure that every reference in your reference list is also cited
in the text. Do not forget to cite
and reference the source of the data.
• When developing your research paper, you may modify the
topic, problem, and research questions.
However, the minimum requirements for the method of analysis
cannot be altered.
• Ensure that you make the research yours and complete this
assignment independently.
• There are several different versions of this assignment. If you
complete a version of this assignment
that is not available to you in Blackboard, you will violate your
pledge.
• If you are concerned about how long the model is taking to
run, you have a few options.
o With the library GuessCompx, you can use the function
CompEst() to evaluate the complexity
and time it will take to process the function. Some things have
10. to be done to the setup to use
this methodology, though.
▪ Example:
If the original model is called
model <-
train(outcome~.,data=d,subset=trainer,importance=T,method=”r
f”)
You would rewrite this as
f <- function(d)
train(outcome~.,data=d,subset=trainer,importance=F,method=”r
f”)
CompEst(d=d,f=f,random.sample=F)
o With the library doParallel, you can use the functions
makePSOCKcluster() and
registerDoParallel() you can run models in parallel, to improve
performance.
▪ Prior to processing the model, use the following as an
example, use help or Google to
learn more. This will maximize the processor power.
cl <- makePSOCKcluster(4) # the value is the number of
processor cores in your device
registerDoParallel(cl)
model <-
train(outcome~.,data=d,subset=trainer,importance=T,method=”r
11. f”,allowParallel=T)
stopImplicitCluster()
registerDoSEQ()

I. Exclusion of Metrics in Predicting Social Vulnerability Index
· Makes it hard for the CDC to calculate the level of aid
required
· The subjects being studied may not give enough detail on
language limitation
· Assessment of the vulnerability of a community in case of a
disaster requires more well-defined metrics.
12. II. Statement of the Problem
Every community needs independent evaluation to find out the
vulnerability of the said area. Two of the contributing factors
for this analysis are language limitations and minority status.
The information may lack credibility because of the fear of
reprisal for individuals that fall into these categories.
Exploration of the physical and social characteristics, excluding
these metrics, can offer insights on the general impact of the
Social Vulnerability Index.
III. Research Methodology
The methods utilized to gather information for addressing the
research problem and the questions that stem from it will be
qualitative. The reports released by the CDC in the year 2018
will play an important role in helping the researcher get the
right information.
IV. Results
The results of the study will be achieved by coding and tallying.
The researcher will source data from different reports and
attempt to find similarities in what challenges the exclusion of
metrics pose in the determination of community SVIs.
V. Impact of the Results
The results will be helpful in assisting future
researchers/stakeholders within and without the CDC to use
different skills so as not to exclude important data set aspects.
VI. Recommendations for Future Analysis
The recommendations that this research will propose to revolve
around using the most significant possible samples and the
blinding of respondents. In this way, it will be simpler to ward
off the possibility of respondent bias. In addition to that,
statistical validity will also be guaranteed.
VII. Conclusion
The conclusion section of the paper will summarize the content
of the entire paper from the introductory section to the
recommendations section.
There are many ways to misrepresent data through
13. visualizations of data. There are a variety of websites that exist
solely to put these types of graphics on display, to discredit
otherwise somewhat credible sources. Leo (2019), an employee
of The Economist, wrote an article about the mistakes found
within the magazine she works for. Sosulski (2016) wrote an
entry in her blog that highlights misrepresentations, as well.
After reading these two articles, create two visualizations in R
that show identical data. In one, create a subtle
misrepresentation of the data. In the other remove the
misrepresentation. Add static images of the two visualizations
to your post. Provide a description of the data and how the
visualizations were created in R.
When adding images to the discussion board, use the insert
image icon.

Considerations for every forum:
Remember your initial post on the main topic should be posted
by Wednesday 11:59 PM (EST). Your 2 following posts should
be commenting on your classmates’ post by Sunday 11:59 PM
(EST). You should end the week with 3 total discussion posts.
14. Your initial post should include your references, thoroughly
present your ideas, and provide evidence to support those ideas.
A quality peer response post is more than stating, “I agree with
you.” State why you agree with your classmate’s post. The
purpose of the forum is generate discussion. You could post
some examples or find a related topic on the Internet or
University’s library and comment on it in the discussion post.
No credit will be earned for posts that are disrespectful or not
on the topic of the forum.
Ensure you read all of this information for the first assignment.
1) The assignment instructions are in a separate file named
Assignment 1 Instructions.
2) When you finish your assignment, submit the research paper
and programmed R Script here. You are not done yet!!
3) After submitting assignment 1 here, open the Assignment 1
Peer Review. After you enter, follow the prompts. The system
will ask that you copy and paste parts of your research paper
into Blackboard.
For the assignment due next Thursday, you will
revisit Assignment 1 Peer Review. When you enter next week
you will not be prompted to answer questions about your
research. You will be prompted to evaluate a peer's responses to
the prompts. If you do not submit your responses this week, you
will not be able to provide a peer review next week, forfeiting
the points for that assignment.
