Predictive models trained on historical data can perpetuate or amplify discrimination. A hiring algorithm trained on past successful employees might exclude qualified women if the company’s history is male-dominated. Ethical analytics requires continuous auditing for disparate impact.

Together, these three tiers form a decision-making continuum. A student studying from a McGraw Hill business analytics textbook would learn that moving from descriptive to prescriptive capability requires not only statistical skill but also organizational alignment and data infrastructure. Although I cannot reproduce proprietary McGraw Hill case studies, public-domain examples mirror the pedagogical models used in such texts.

answers, “What happened?” Through dashboards, key performance indicators (KPIs), and data visualization tools, it provides a historical lens. For example, a retailer might use descriptive analytics to identify which product categories generated the highest revenue last quarter. While essential for reporting, descriptive analytics alone cannot guide future strategy.

Amazon’s fulfillment centers rely heavily on predictive analytics to forecast demand for millions of SKUs. By analyzing historical sales, seasonal trends, and even weather patterns, the company positions inventory closer to anticipated buyers. This reduces shipping times and costs—a classic application of predictive analytics leading to prescriptive inventory rebalancing.
