It builds statistical thinking through practical examples and a structured progression from data basics and sampling to probability, distributions, and core inference. Readers learn to summarize numerical and categorical data, interpret confidence intervals and perform hypothesis tests, and handle inference for categorical and numerical outcomes. The book culminates with linear, multiple, and logistic regression, supported by exercises and reference
