Assignment 6
PS 3780 Data Literacy & Visualization, Autumn 2022
Due Date: Friday, March 10, 2023 at 11:59 p.m.
Please save your visualizations and answers to these questions as one .pdf
le (use the save as function in most word processors). Be sure to include your name,
your teammate’s name if there is anyone, and the assignment number. Submit the le
to Carmen by the due date. Remember we are looking for professional visualizations so
please include a meaningful title as well as axis labels and a legend.
Presidential Approval
Return to 538 to download the presidential approval data for President Biden. Scroll to
the bottom of the page and click on polls” to get the proper dataset. Load this dataset
into R and subset the dataset to only include polls where the `Subgroup’ column
has a value of All polls”.
We are going to explore the Net Approval and Approval Ratio.
Net Approval is
the dierence between approval and disapproval. Approval Ratio is approval divided by
disapproval. You created these variables in Assignment 3; do it again for this updated
dataset by using the same code as before.
Create two visualizations to address the theory of the presidential honeymoon eect:
one for Net Approval and one for Approval Ratio. Scholars suggest that new presidents
have a short period of time at the beginning of their presidency when they are not
overly criticized. The period of time may range from 30 to 100 days. After the period,
presidential approve quickly reacts to what was accomplished in that period and opinion
becomes more reective of presidential action. This tends to lead to decreasing approval
as it is dicult for presidents to make quick unilateral change. Select a time length within
the proposed period to visualize the honeymoon eect for President Biden. With a plot
and a paragraph for each plot, use the polling data from the most common polling agencies
to suggest whether your chosen honeymoon length ts the theory for each dependent
variable. Make sure your visualization includes the following features. (6 pt)
ˆ Include only polling agencies that have reported more than 70 polls for the All
Polls” group (there should be 4).
ˆ Include a vertical reference line at the date where you think the honeymoon may
have ended (how many days).
ˆ Include a horizontal reference line at a key value of the dependent variable (what
is `even’ for Net and Ratio)
1
ˆ Include separate trend lines for pre- and post-honeymoon polls from each agency
(a total of 8 trend lines).
ˆ Scatterplot points can be suppressed for clarity.
ˆ Include a title, axis labels, and a legend.
ˆ Your paragraphs should analyze your visualization and then make a conclusion
about the theory.
