This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.
When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
summary(cars)
## speed dist
## Min. : 4.0 Min. : 2.00
## 1st Qu.:12.0 1st Qu.: 26.00
## Median :15.0 Median : 36.00
## Mean :15.4 Mean : 42.98
## 3rd Qu.:19.0 3rd Qu.: 56.00
## Max. :25.0 Max. :120.00
You can also embed plots, for example:
Note that the echo = FALSE parameter was added to the
code chunk to prevent printing of the R code that generated the
plot.

Prompt: in the tutorial, we calculated the average trust in others for France and visualized it. Using instead the variable ‘Trust in Parliament’ (trstplt) and the country of Spain (country file provided on course website), visualize the average trust by survey year. You can truncate the y-axis if you wish. Provide appropriate titles and labels given the changes. What are your main takeaways based on the visual (e.g., signs of increase, decrease, or stall)?

Answer: The average trust seems to reach its peak in at the start
(2004), but gradually decreases until it starts to slowly and steadily
increase again. Near the end of the visual in 2020, the average starts
decreasing again.

Prompt and question: Based on the figure we produced above called task2_plot, tell us: what are your main takeaways regarding France relative to Italy and Norway? Make sure to be concrete and highlight at least two important comparative trends visualized in the graph.
Answer: One important comparative trend that seperates France from Italy and Norway is that France experienced a much steeper decrease in proportion than both Italty and Norway. Based on the visual France’s proportion saying ‘yes’ saw the largest decline, and this can be seen by comparing and looking at the difference between the peak point and lowest point. Another main takeaway is that while Italy and Norway see an slight decrease/stall in proportion, France sees an increase and reaches a peak for these same cohort years (1920 to around 1945).
Provide code and answer.
Question: What is the marginal percentage of Italian men who feel close to a particular political party?

Marginal Percentage:
Answer: 20.5% of all Italian respondents are males who feel close to a particular political party .

Provide code and answer: In Hungary, what is the conditional probability of NOT feeling close to any particular party given that the person lives in a rural area?

## 3 1 Rural 5055 0.446
## 4 1 Urban 2283 0.488
Answer: The conditional probability of NOT feeling close to any particular party given that the person lives in a rural area is 55.4%
Given that a person does NOT feeling close to any particular party there is a 55.4% probability that they live in a rural area.
