Exercise

Observing categoricals

Remember from the previous exercise that:

  • Ordinal variables have two or more categories which can be ranked or ordered
  • Nominal variables have two or more categories which do not have an intrinsic order

In your dataset:

  • salary is an ordinal variable
  • department is a nominal variable

In this exercise, you're going to observe the categorical variables found in the previous exercise. To do that, first of all, you will import the pandas library and read the CSV file called "turnover.csv". Then, you will print the unique values of those variables.
