Where this leads in business & finance

Statistics is the single most directly employable subject on this list. Risk, pricing, forecasting, A/B testing, credit scoring, fraud detection and portfolio construction are all applied statistics. Actuaries — consistently among NZ's best-paid professions — are essentially professional statisticians. And 91584 is training in something rarer than technique: the judgement to spot when a number is being used to mislead. In business that skill protects you from bad investments, bad consultants and bad strategy decks.
