Overview

Essential Statistics for Economics, Business and Management is an indispensable text for students taking an introductory undergraduate course in statistics, as well as being highly relevant for the statistics component of courses in quantitative methods.

Key Features:

  • Assumes no prior knowledge of statistics
  • Emphasis is placed on verbalising concepts, problems and results of statistical analysis, thereby helping students to learn how to start a problem, complete calculations and report results in a way that will make sense to a non-statistician.
  • Each concept is introduced with a brief and plausible explanation followed by worked examples. The worked examples provide students with the necessary practice that they need in order to succeed at the subject.
  • Excel and Minitab are used throughout the text to introduce students to statistical software and enhance understanding.
  • Progress exercises on theory and applications are provided at the end of each section for students to test their knowledge.

The accessible style of the text is consistent with that of the highly successful Essential Mathematics for Economics and Business, also by Teresa Bradley and published by John Wiley & Sons, Ltd.

 A comprehensive website to support the book has been produced and includes: PowerPoint slides, datasets, further worked examples, a testbank for lecturers, and additional test exercises for students.
