What are qualitative data?
Qualitative, or categorical, data, in contrast to quantitative data, refers to all data that are not numbers. This can include strings (for example, names) or booleans (True/False, yes/no, 1/0, etc.).
Qualitative data can also be plotted using the tools seen previously. However, there is an all-in-one tool that makes it easy to switch between different plot styles.
