Instruction

Now let's analyze the values found in the wealth_index and consumption variables. We will want answers to these questions:

  • Is there a relationship between a country's wealth and its alcohol consumption?
  • What is the relationship? Do wealthier countries drink more or less alcohol than the others?
  • Are there any untypical countries or groups of countries? For example, are there wealthy countries with a high consumption of alcohol when most wealthy countries have a low consumption?
  • What values does each variable take? What are the minimal and maximal levels of alcohol consumption and wealth in the country?
  • Which is the most frequent value?
