Data Science & Analytics Department

Every Nigerian bank, hospital, retailer and government agency now collects more data than it can read. Our Data Science & Analytics department trains you to close that gap: clean messy spreadsheets, query databases with SQL, build executive dashboards in Power BI, and run predictive models in Python. Every module ends with a portfolio deliverable built on real Nigerian data — NBS, CBN, open health and commerce datasets — so your work looks like the job before you have the job.

Data Science & Analytics — frequently asked questions

Do I need to be good at mathematics?

Secondary-school mathematics is enough to start. We teach the statistics you need module by module, applied to real datasets rather than as theory.

Is Power BI or Tableau better for jobs in Nigeria?

Power BI appears in far more Nigerian job adverts because of Microsoft 365 adoption. We teach it first, then Tableau and Looker Studio for coverage.
