**No — in data science, expected value can be fractional** Why are more professionals and businesses sitting up and taking notice? The idea that decisions based on uncertain outcomes can carry a value that isn’t whole numbers—no, fractional—may seem subtle, but it’s reshaping how risk, investment, and prediction are approached across industries. In data science, *no* isn’t a dead end; it’s a tool for greater precision. At its core, expected value—traditionally seen as a whole number—measures the average outcome when outcomes carry uncertainty. But when probability is uneven or sparse, using whole numbers overlooks critical nuances. Recognizing that *no* can reflect a precise fractional value allows models to capture partial outcomes, uncertain bets, and asymmetric risks more accurately. This subtle shift challenges old assumptions and opens more realistic paths forward. Why is this gaining traction now, especially in the US? Growing complexity in financial markets, healthcare resource planning, and AI-driven forecasting has created demand for models that don’t force outcomes into rigid categories. Businesses and data teams increasingly seek ways to price uncertainty clearly—without oversimplifying—making fractional expected value a practical advancement.
