preface

Data-driven decision-making has become a cornerstone of modern business, technology, and scientific research. Whether predicting financial trends, detecting potentially fraudulent activity, or managing large-scale projects, quantitative methods provide the foundation for solving complex problems with confidence. Yet, too often, critical decisions are made without using these powerful techniques, relying instead on intuition, tradition, or incomplete analysis. This needs to change. The ability to apply statistical reasoning and optimization methods is no longer a specialized skill: it is an essential competency for professionals in every data-driven field.
