Exercise

Filtering rows

The vote column in the dataset has a number that represents that country's vote:

  • 1 = Yes
  • 2 = Abstain
  • 3 = No
  • 8 = Not present
  • 9 = Not a member

One step of data cleaning is removing observations (rows) that you're not interested in. In this case, you want to remove "Not present" and "Not a member".
