  3. Summarise with numbers

    Use totals, averages and groups to describe what the data shows.

  4. Show it with a chart

    Choose a chart that answers your question at a glance.

  5. Tell the story

    Explain what you found, why it matters and what to do next, in plain words.

  6. Final project

    Answer one real question with a small dataset: clean it, summarise it, chart it and explain the finding.

Questions

All questions
Is the same course the same for everyone?

The modules and what you are checked against are the same, so everyone learns the same skills. How each lesson is explained, and the examples it uses, change for you.

Do I need any experience?

No. Every course starts from the basics. If you already know some of it, an optional two-minute check lets you skip ahead.
