Getting ready

Discrete variables are usually of the int type, continuous variables are usually of the float type, and categorical variables are usually of the object type when they're stored in pandas. However, discrete variables can also be cast as floats, while numerical variables can be cast as objects. Therefore, to correctly identify variable types, we need to look at the data type and inspect their values as well. Make sure you have the correct library versions installed and that you've downloaded a copy of the Titanic dataset, as described in the Technical requirements section.
