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:

## 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 and question: calculate the average for the variable ‘happy’ for the country of Norway. On average, based on the ESS data, who reports higher levels of happiness: Norway or Belgium?
Note: we already did it for Belgium. You just need to compare to Norway’s average, making sure to provide the code for both.

Prompt and question: what is the most common category selected, for Irish respondents, for frequency of binge drinking? The variable of interest is: alcbnge.
More info here: https://ess-search.nsd.no/en/variable/0c65116e-7481-4ca6-b1d9-f237db99a694.
Hint: need to convert numeric value entries to categories as specified in the variable information link. We did similar steps for Estonia and the climate change attitude variable.

Prompt and question: when you use the summary() function for the variable plnftr (about planning for future or taking every each day as it comes from 0-10) for both the countries of Portugal and Serbia, what do you notice? What stands out as different when you compare the two countries (note: look up the variable information on the ESS website to help with interpretation)? Explain while referring to the output generated.

Answer: One big thing that stands out to me is that Serbia’s 1st Quartile is 0. This means that 25% of all voters voted for taking each day as it comes, compared to portugual which has a value of 3 at the 1st quartile. Overall (and indicated by the mean) Portugal leans toward planning more for the future, and Serbia leans a little bit more towards taking each day as it comes.

Prompt and question: using the variables stfdem and gndr, answer the following: on average, who is more dissastified with democracy in Italy, men or women? Explain while referring to the output generated.
Info on variable here: https://ess.sikt.no/en/variable/query/stfdem/page/1
italy_data <- ess %>%
filter(cntry == "IT")
italy_data <- italy_data %>%
mutate(
gndr = case_when(
gndr == 1 ~ "Male",
gndr == 2 ~ "Female",
TRUE ~ as.character(gndr)
),
)
table(italy_data$gndr)
##
## 9 Female Male
## 13 5329 4836
italy_data$gndr[italy_data$gndr %in% 9] <- NA
italy_data <- italy_data %>% filter(!is.na(gndr))
means_by_gender <- italy_data %>%
group_by(gndr) %>%
summarize(stfdem = mean(stfdem, na.rm = TRUE))
print(means_by_gender)
## # A tibble: 2 × 2
## gndr stfdem
## <chr> <dbl>
## 1 Female 8.43
## 2 Male 7.43
Answer: since 10 is labeled as extremely satisfied, and 0 is labeled as extremely dissatisfied, males are more dissatisfied with democracy in Italy than women. Males have a mean democracy satisfaction of 7.43 which is lower than females with a mean of 8.43.

Prompt: Interpret the boxplot graph of stfedu and stfhlth that we generated already: according to ESS data, would we say that the median French person is more satisfied with the education system or health services? Explain.
Change the boxplot graph: provide the code to change some of the key labels: (1) Change the title to: Boxplot of satisfaction with the state of education vs. health services; (2) Remove the x-axis label; (3) Change the y-axis label to: Satisfaction (0-10).
Hint: copy the boxplot code above and just replace or cut what is asked.
france_data <- read.fst("france_data.fst")
france_data %>%
mutate(stfedu = ifelse(stfedu %in% c(77, 88, 99), NA, stfedu),
stfhlth = ifelse(stfhlth %in% c(77, 88, 99), NA, stfhlth)) %>%
select(stfedu, stfhlth) %>%
gather(variable, value, c(stfedu, stfhlth)) %>%
ggplot(aes(x = variable, y = value)) +
geom_boxplot() +
labs(y = "Y-axis", x = "X-axis", title = "Boxplot of stfedu vs. stfhlth") +
theme_minimal()
## Warning: Removed 364 rows containing non-finite values (`stat_boxplot()`).
Answer: The median french person is more satisfied with the health
services. The thick and dark line in the middle of the boxes represent
the median of each variable in this boxplot. Since the median line for
education is close to 5, and the median line for health services is
closer to 7, the median for health services is higher. Therefore, The
median for a french persons satisfaction is higher for health
services.
