Task 1

Provide code and answer.

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.

Task 2

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.

Task 3

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.

Interpretation:

Both Portugal and Serbia range from 0-10 indicating that respondents are providing responses across the full spectrum of the range. However, there are less extreme values compared to Portugal, with no outliers. Additionally, the mean values for Serbia :4.983: is slightly higher than the mean in Portugal :4.143:, indicating to a higher level of planning for the future compared to Portugal’s. Overall, both countries contain similar range of responses however the distribution and means establish key distinctions into how both countries approach planning for the future.

Task 4

Provide code and answer.

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$gndr[italy_data$gndr %in% 9] <- NA

      gndr == 1 ~ "Male",
      gndr == 2 ~ "Female",
      TRUE ~ as.character(gndr)
    )

italy_data <- italy_data %>% filter(!is.na(stfdem))

# Compute mean for male
mean_male_stfdem <- italy_data %>%
  filter(gndr == "Male") %>%
  summarize(mean_stfdem_men = mean(stfdem, na.rm = TRUE))

print(mean_male_stfdem)

means_by_gender <- italy_data %>%
  group_by(gndr) %>% # here you are "grouping by" your second variable
  summarize(stfdem = mean(stfdem, na.rm = TRUE)) # here you are summarizing your variable of interest

print(means_by_gender)
## # A tibble: 2 × 2
##   gndr   stfdem
##   <chr>   <dbl>
## 1 Female   4.66
## 2 Male     4.78

Females are more dissatisfied with democracy in Italy

Task 5

Provide code and answer.

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 <- ess %>% 
  filter(cntry == "FR")

france_data %>%
  # Setting values to NA
  mutate(stfedu = ifelse(stfedu %in% c(77, 88, 99), NA, stfedu),
         stfhlth = ifelse(stfhlth %in% c(77, 88, 99), NA, stfhlth)) %>%
  # Reshaping the data
  select(stfedu, stfhlth) %>%
  gather(variable, value, c(stfedu, stfhlth)) %>%
  # Creating the boxplot
  ggplot(aes(x = variable, y = value)) +
  geom_boxplot() +
  labs(y = "Satisfaction (0-10)", x = " ",  title = "Boxplot of satisfaction with the state of education vs. health services") +
  theme_minimal()
## Warning: Removed 364 rows containing non-finite values (`stat_boxplot()`).

The median line within the boxplot of satisfaction with health services is higher, therefore satisfaction with healthcare is higher in France.
