Simple Statistics

Ask a clear question of data. Claim no more than the evidence allows.

Simple Statistics builds a connected foundation in statistics for first-course students in science, engineering, and the social sciences, independent learners, and readers revisiting statistics.

16 chapters. 139 problems with worked solutions. 110 figures. Learn to describe data, reason with chance, estimate with intervals, test claims, and fit a regression line, reading each result for its size and its uncertainty.

Build a connected understanding of:

Questions, variables, study design, and what a design allows you to conclude.

Tables, graphs, center, spread, position, and comparing distributions.

Probability, random variables, the binomial and Normal models, and sampling distributions.

Confidence intervals and hypothesis tests for one and two groups, paired data, one-way ANOVA, and chi-square tests.

Correlation, simple linear regression, and choosing and defending a method.

Attempt-first practice, three cumulative reviews, a mid-book mastery check, and a final review with a capstone case support active learning and independent method selection.

An essential-equations reference with a method map, a glossary, further-learning references, and an index support review. Examples use constructed teaching data and real field data on penguins.

The starting level is arithmetic, percentages, and school algebra. A calculator or spreadsheet is enough for Normal areas.
