Instruction

Earlier, you learned how to recognize different types of variables. We will now use this knowledge to better understand the alcohol_wealth dataset.

Have another look at the variables:

  • country - The name of the country,
  • consumption - The number of liters of pure alcohol consumed per adult,
  • wealth_index - An indicator of the wealth of the country, per the World Bank.

Think about how you'd classify each of these variables. Are they categorical or numerical?
