Exercise

Selecting specific data types

Often a data set will contain columns with several different data types (like the one you are working with). The majority of machine learning models require you to have a consistent data type across features. Similarly, most feature engineering techniques are applicable to only one type of data at a time. For these reasons among others, you will often want to be able to access just the columns of certain types when working with a DataFrame.

The DataFrame (so_survey_df) from the previous exercise is available in your workspace.
