ISBN: 9798172985607 - business statistics and data analytics: practical methods for data-driven decisions, forecasting, and business intelligence (4 résultats)

Taschenbuch. Etat : Neu. Neuware - Software can produce an answer in seconds - but can you explain whether the answer is trustworthy, relevant, and worth acting on Organizations collect more data than ever before, yet the gap between data and sound decisions keeps widening. Managers copy output into reports without checking assumptions. Analysts run tests without understanding what the test actually claims. Students pass exams by memorizing formulas but freeze when asked to interpret results for a real audience. The missing ingredient is not more computation. It is statistical judgment: the ability to frame the right question, recognize the limits of the evidence, and communicate uncertainty without hiding it.This textbook builds that judgment from the ground up. It connects every method - from descriptive measures through probability, sampling, estimation, hypothesis testing, regression, forecasting, and analytics - to the assumptions behind it, the interpretation it supports, the mistakes it invites, and the managerial consequences of getting it wrong. Hundreds of worked examples use realistic United States business settings and walk through every step, not to show the shortcut but to show the reasoning.What this book helps you develop: - The ability to frame a question before selecting a method, so the analysis answers the decision that matters.- Confidence reading and explaining output rather than copying numbers into a table.- The judgment to distinguish a meaningful pattern from normal variation, a correlation from a cause, and a forecast from a guarantee.- Practical skill with estimation, testing, regression, and time-series methods, built through step- by-step worked examples and practice problems with full answer keys.- An understanding of responsible analytics - ethics, reproducibility, bias, fairness, and executive communication - as integral parts of the workflow.Key topics: the analytics continuum; collection and sampling design; visualization; descriptive measures; probability and distributions; the central limit theorem; confidence intervals; hypothesis testing; analysis of variance; correlation and regression; multiple regression and predictive modeling; time-series analysis; KPIs, dashboards, ethics, reproducibility, and executive communication.Who it is for: undergraduate courses, graduate-entry programs, professional development, and independent study. No prior course is required - only basic arithmetic and elementary algebra.Start building the statistical judgment that turns evidence into responsible action - add this resource to your library and begin with the decision that matters most to you.…
