Essential Statistics, 3rd Edition is the textbook that covers the fundamental concepts of introductory statistics using real data. Authors Robert Gould and Rebecca Wong first explain exploratory data analysis and inferential statistics. In the final chapters, they present themes covered earlier in a new context and introduce additional statistical methods, including estimating population means and analyzing categorical variables.

To prepare you for success in our data-driven world, the textbook shows how to summarize data sets, run and interpret hypothesis tests, build confidence intervals, and analyze data with StatCrunch, Excel, or a TI calculator. The authors provide detailed instruction in probability, hypothesis testing, goodness-of-fit, inferences from two samples, discrete and normal probability distributions, and correlation and regression, along with describing and exploring data and estimating parameters and confidence intervals.

Inspired by the Guidelines for Assessment and Instruction in Statistics Education (GAISE), the 3rd Edition reflects the rise of data science, with new features to prepare you for working with complex data.
