# Discovering Statistics Using IBM SPSS Statistics

- Andy Field - University of Sussex, UK

With an exciting new look, new characters to meet, and its unique combination of humour and step-by-step instruction, this award-winning book is the statistics lifesaver for everyone. From initial theory through to regression, factor analysis and multilevel modelling, Andy Field animates statistics and SPSS software with his famously bizarre examples and activities.

What’s brand new:

- A radical new design with original illustrations and even more colour
- A maths diagnostic tool to help students establish what areas they need to revise and improve on.
- A revamped online resource that uses video, case studies, datasets, testbanks and more to help students negotiate project work, master data management techniques, and apply key writing and employability skills
- New sections on replication, open science and Bayesian thinking
- Now fully up to date with latest versions of IBM SPSS Statistics©.

All the online resources above (video, case studies, datasets, testbanks) can be easily integrated into your institution's virtual learning environment or learning management system. This allows you to customize and curate content for use in module preparation, delivery and assessment. For instructions on how to upload the resources you want, please visit the Instructors' page or alternatively, contact your local SAGE sales representative.

Please note that ISBN: 9781526445780 comprises the paperback edition of the Fifth Edition and the student version of IBM SPSS Statistics. More information on this version of the software's features can be found here.

### Supplements

This book turned my hatred of stats and SPSS into love.

**MSc in Applied Quantitative Methods**

brilliant book,

well written and easy to remember examples.

stats with a sense of humor

**Psychology, Fachhochschule des Mittelstands (FHM)**

This is a great book for learners with minimal previous experience in statistics. The examples and case studies provided throughout the book are very effective and learners will find them memorable. Easy to use, practical and a must have for anyone serious about learning to analyse their data using SPSS.

**Centre for International Development, Wolverhampton University**

In Germany we have several books on methods and statistics using SPSS. Andy Field's book is the best book since years, even if our English is not the best. It is a careful introduction which can be used in courses as well as for our daily work in empirical projects. Additionally it helps to find solutions for complicated statistical questions even for researchers which are highly experienced. Thanks to editors and Andy Field to continue this project.

**Faculty of Education, University of Bielefeld**

Highly informative and accessible style of writing. It will be a delight for students to discover.

**School of Modern Languages & Applied Linguistics , University of Limerick**

excellent new edition

**Department of Psychology and Counselling, Chichester University**

Essential text for all students who use SPSS...at UG and PG level

**Sport, Physical Education & Leisure, University of St Mark And St John**

I write this review full of jealousy: I wish I could write and teach like Andy Field. We are using "Discovering Statistics" in stats courses, and both the reactions from students and teaching staff are overwhelmingly positive. Being no statistician, Andy manages to offer a low-threshold and low-threat approach to statistics that many other textbooks (written by 'real' statisticians) fail to realise. Inane examples and a solid background in NWOBHM surely help. The only downside of the book is that when I read it, I realise what an excellent teacher Andy is (and I am not).

**Community Health, University of Bremen**

I recommend this book not only for my market research course, but also for students who write their master's and bachelor's theses with me.

The reason for my explicit recommendation is that the author explains the basics of statistics using very vivid examples. The structure of the book contributes to a better understanding. For individual questions, it is possible to read the chapters independently of each other, which makes the book a perfect encyclopedia. It is great that the applications and syntax in SPSS are also explained transparently.

**Wirtschaft & Medien, Hochschule Fresenius University of Applied Sciences**

A very good textbook which arouses the interest of readers and includes a large range of resources which actively engage them in the learning process.

**School of Education, Oxford Brookes University**
