Data Analyst: Turning Information into Better Decisions

Every organisation collects information, but information only becomes valuable when someone can interpret it. Data analysts clean, organise and examine data so that decision-makers can understand what is happening, why it may be happening and what action to consider next.

What does this professional do?

• Collects data from spreadsheets, databases, surveys and business systems.
• Checks data for missing, duplicated or incorrect information.
• Uses statistics and analytical tools to identify patterns and trends.
• Builds dashboards, graphs and reports using tools such as Excel, Power BI, Tableau or similar platforms.
• Explains findings clearly and recommends practical next steps.

Could this career suit you?

Data analysis can suit someone who is curious, logical and attentive to detail. It is not only about numbers. Analysts must ask good questions, understand the business problem and communicate findings to people who may not have a technical background.

Helpful school subjects

Mathematics is particularly valuable. Information Technology, Computer Applications Technology, Business Studies, Accounting, Economics and languages can also help develop technical, commercial and communication skills. Admission requirements vary by qualification and institution.

Study and development routes

Common study routes include statistics, data science, computer science, information systems, business analytics, economics, finance or mathematics. A diploma or degree can be supported by practical training in spreadsheets, SQL, data visualisation and basic programming. Build a portfolio using public or self-created datasets and explain the question, method, visualisation and conclusion for each project.
