With a focus on presenting basic statistical concepts in a friendly and accessible style, this book focuses on the more subjective side of statistics-the art of data analysis. It provides fun, common sense examples that explore statistical concepts and methods and is aimed at helping anyone who has to make decisions based on raw data or compiled results. It also introduces basic concepts like descriptive statistics and regression and addresses important issues that tend to complicate analysis such as skewed distributions and outliers.

KRISTIN H. JARMAN, PhD, is Senior Research Scientist at the Pacific Northwest National Laboratory in Richland, Washington, where she applies basic and not-so-basic statistical analyses to her own set of research challenges.
