Data Analysts turn raw data into actionable insights by collecting, cleaning, transforming, and analyzing information to answer “what happened” and guide business decisions.
They sit within the Business Intelligence & Analytics ecosystem, building the pipelines and workflows that feed dashboards and reports for stakeholders.
To start, you’ll need strong foundations in statistics, SQL, and spreadsheet tools; then you’ll learn programming (Python or R), data visualization, and domain knowledge (CareerFoundry, iSchool | Syracuse University).
After that, you can specialize in advanced analytics, BI tooling, or move toward Data Science and management roles (Coursera).
With data roles projected to grow 36% by 2033, a Data Analyst career is robust and future-proof .
