Welcome to Data

What data is, why it matters, and how this course is structured.

About This Module

This module teaches you the fundamentals of working with data — what it is, how it moves, how to clean it, and what roles exist around it. It is designed to come before tools like Excel, SQL, and Python.

  • 16 lessons covering data concepts, quality, ethics, and roles
  • Each lesson has explanations, examples, and a section check
  • Every lesson ends with a 7-question quiz
  • No maths or programming required — just clear thinking

Think of this as the map before the journey. You will understand why every tool you learn later exists.
