Introduction to
Data Science

Data science is not a library you import. It is the discipline of taking a raw, awkward, incomplete file and turning it into something a person can actually decide with — and knowing, at every step, how much you are entitled to claim.

The notes for this course
are on their way.

This page is deliberately empty for now. I publish each lesson only after we have covered it in class, so that what you read here matches exactly what was taught — the same datasets, the same code, the same worked examples.

Keep this link. Check back after every session, and you will always find the latest material waiting here.

  • What data science actually is — and the honest difference between it, statistics and analytics.
  • Collecting and storing data — files, tables, formats, and where things go wrong first.
  • Cleaning — missing values, duplicates, wrong types, and the unglamorous work that decides everything.
  • Exploratory analysis — asking a dataset good questions before you assume any answers.
  • Visualisation — charts that reveal rather than decorate, and the ones that mislead.
  • A first model, and communicating it — a simple prediction, and how to present it without overclaiming.
