### Elementary Statistics In Social Research: The Essentials by Jack A. Levin

Adapted from the best-selling Elementary Statistics in Social Research, 9/e by Levin/Fox ((c) 2003), this exciting new resource provides a concise, uncomplicated introduction to statistics for the social sciences. Written to be understandable to a broad range of readers, particularly those without a strong background in mathematics, the book provides clear, logical explanations for the rationale and use of statistical methods in social research. Detailed step-by-step illustrations of statistical procedures are located at important points throughout the text.

Each chapter concludes with Summary, and Questions and Problems.
