Quantitative & Qualitative Variables (Pilot)

SUMMARY

This lesson introduces quantitative and qualitative variables, two fundamental ways to classify data—the foundational building block of data science. Understanding these variable types is the first step toward effectively applying machine learning methods and tools.

In this session, we’ll explore:

1. What quantitative and qualitative variables are.
2. How to differentiate them and why we need to do that.
3. Common types of quantitative and qualitative variables, along with practical examples of each type.
