Sinopse:
If statistics has ever felt like a blur of formulas and misleading headlines, this textbook starts by grounding the reader in the basics that make everything else intelligible. Its table of contents moves from one-variable statistics into the core language of the subject, then builds through bar charts, histograms, stem-and-leaf plots, measures of center, spread, outliers, and the five-number summary before turning to bi-variate statistics and scatterplots. The book is clearly the work of a single author, Jonathan A. Poritz, and it reads like a full one-semester undergraduate course built from the ground up. The later chapters widen the scope from correlation and linear regression into probability theory, conditional probability, random variables, the normal distribution, and the logic of collecting good data through studies, experiments, ethics, and randomized controlled trials. What makes it especially useful is the way it connects descriptive statistics to inference without skipping the foundations: the central limit theorem, confidence intervals, and hypothesis testing are all introduced after the reader has already learned how to describe data honestly and carefully. It is an introductory textbook, but one with a strong critical-thinking angle, aimed at helping students recognize both the power and the misuse of statistical reasoning.
