UNDERSTAND THE WORK

What does a Data Analyst actually do?

Data Analyst investigates information to help people answer specific questions. The job is about understanding the problem before choosing tools: who needs the result, how will success be measured, and what could go wrong?

Imagine this workplace situation: A local council wants to understand why recycling rates vary between neighbourhoods.

A good specialist does more than finish a task. They explain decisions, test their work and communicate what the evidence does—or does not—show.

Typical work and responsibilities

Check how a dataset was collected.
Clean missing or inconsistent entries.
Create charts and explain the limits of a finding.

What makes the role different? Data Analyst primarily investigates information to help people answer specific questions. Related careers may use the same tools but solve different problems.

Skills worth developing at school

Spreadsheets and SQL.
Charts and basic statistics.
Clear written explanations.

Build your explanations and teamwork alongside technical knowledge. Being able to justify a choice is often as important as selecting the right software.

One misconception to avoid

A chart can show a relationship without proving what caused it.

Investigate that limitation in a project: give yourself a test case, record the results and explain what you would do differently next time.

Your Data Analyst mini challenge

Compare a fictional school travel survey across year groups. Identify a pattern and one possible bias.

What should you produce?

A labelled chart, three evidence-backed findings and one caveat.

Show your thinking: include a screenshot, table, sketch or short explanation, then record one improvement you would make after feedback.

For your portfolio: write three sentences describing the question you tackled, the evidence you gathered, and the limitation you discovered.
