Develop confidence conducting statistical analysis with this trusted text

Understanding Statistics in Psychology with SPSS, eighth edition, by Dennis Howitt and Duncan Cramer is the comprehensive guide that helps you conduct statistical analyses using SPSS with confidence.

Combining coverage of statistics with full guidance on how to use SPSS to analyse data, the book's straightforward content is neatly organised into short, accessible chapters that can be used in class or for independent study. Clear diagrams and full colour screenshots from SPSS make the text suitable for beginners, while the broad coverage of topics helps you progress to more advanced techniques.

This edition provides an engaging learning aid packed with examples from real psychological studies that illustrate how statistical techniques are used in practice. Learning features including key concept boxes, 'focus' sections and 'explaining statistics' sections ensure solid understanding of underpinning principles.

This trusted book is the ideal companion for undergraduate students in psychology.
