This revision guide book covers the major areas of Statistical Analysis covered in Undergraduate Psychology. The focus is on the practical application of statistics to assignments and assessments that you may encounter. To ensure that you are able to apply statistics, particular attention is given to the key concepts you need to understand in order to be able to use statistics correctly; the process you need to follow in order to choose the correct statistic; and what you need to do to present and interpret your statistics correctly. The coverage of the individual tests focus on pragmatic issues, such as when the test is appropriate, how to format data correctly and what to do when you don't get the data you expect. You are directed to further readings for the mathematical underpinnings of the statistical tests. Examples and case studies are used throughout, so you can see the application of statistics to problems that are similar to those you are likely to encounter. Features focused on critical thinking, practical applications and key research will offer additional pointers for you in your revision process/exam preparation. A companion website provides supporting resources for self testing, exam practice, answers to questions in the book, and links to further resources.
