Key Concepts Covered in the Book
Discovering Statistics Using IBM SPSS Statistics (2013) is like a treasure chest of statistical knowledge. Andy Field meticulously covers a wide array of essential concepts that form the bedrock of statistical analysis. Let's unearth some of the key areas you'll explore in this book.
First off, you'll get a solid grounding in descriptive statistics. This includes measures of central tendency (mean, median, mode) and measures of dispersion (standard deviation, variance, range). Understanding these concepts is crucial for summarizing and describing your data in a meaningful way. Field doesn't just throw formulas at you; he explains the intuition behind each measure, helping you grasp why they're important and how to interpret them.
Next up is inferential statistics, where you'll learn how to make inferences about populations based on sample data. This section covers hypothesis testing, which is the cornerstone of scientific research. You'll learn about null and alternative hypotheses, p-values, and statistical significance. Field walks you through the process of formulating hypotheses, choosing the appropriate statistical test, and interpreting the results. He also emphasizes the importance of understanding Type I and Type II errors, which can help you avoid drawing incorrect conclusions from your data.
The book also delves into correlation and regression. Correlation helps you understand the relationship between two or more variables, while regression allows you to predict the value of one variable based on the value of another. Field explains different types of correlation (e.g., Pearson, Spearman) and regression (e.g., linear, multiple) and provides guidance on how to interpret the results. He also covers important topics like multicollinearity and model fit, which are essential for building accurate and reliable regression models.
Analysis of Variance (ANOVA) is another key concept covered in the book. ANOVA is used to compare the means of two or more groups. Field explains different types of ANOVA (e.g., one-way, two-way, repeated measures) and provides guidance on how to choose the appropriate test for your research question. He also covers post-hoc tests, which are used to determine which groups differ significantly from each other.
Finally, the book touches on non-parametric statistics, which are used when the assumptions of parametric tests are not met. Field explains different non-parametric tests (e.g., Mann-Whitney U test, Wilcoxon signed-rank test, Kruskal-Wallis test) and provides guidance on how to choose the appropriate test for your data. He also emphasizes the importance of understanding the limitations of non-parametric tests.
In addition to these core concepts, Discovering Statistics Using IBM SPSS Statistics (2013) also covers a range of more advanced topics, such as factor analysis, cluster analysis, and time series analysis. Whether you're a student, researcher, or professional, this book will equip you with the knowledge and skills you need to tackle a wide range of statistical challenges.
How the 2013 Edition Differs
The 2013 edition of Discovering Statistics Using IBM SPSS Statistics isn't just a rehash of previous versions; it's a significant update that reflects advancements in statistical methods and software capabilities. One of the most notable differences is the expanded coverage of multivariate analysis. This includes techniques like factor analysis, cluster analysis, and discriminant analysis, which are used to analyze complex datasets with multiple variables. Field provides clear explanations of these techniques, along with practical examples and step-by-step instructions on how to perform them using SPSS.
Another key difference is the increased emphasis on effect sizes and confidence intervals. While p-values are still important, there's a growing recognition that they don't tell the whole story. Effect sizes provide a measure of the magnitude of an effect, while confidence intervals provide a range of plausible values for a population parameter. Field explains how to calculate and interpret effect sizes and confidence intervals, and he encourages readers to report them alongside p-values in their research reports.
The 2013 edition also includes updated examples and datasets that reflect current research trends. Field draws on real-world examples from a variety of fields, such as psychology, sociology, and business, to illustrate the practical application of statistical methods. This helps readers see how statistics can be used to answer important questions in their own areas of interest.
Furthermore, the book has been updated to reflect changes in the SPSS software. Field provides screenshots and instructions for the latest version of SPSS, ensuring that readers can easily follow along with the examples and exercises. He also includes tips and tricks for using SPSS more efficiently.
Compared to earlier editions, the 2013 version has improved clarity and organization. Field has reorganized some of the chapters to make the material flow more logically. He has also added more headings and subheadings to make it easier for readers to navigate the book. The writing style is also more concise and engaging, making the book more accessible to a wider audience.
In summary, the 2013 edition of Discovering Statistics Using IBM SPSS Statistics is a significant improvement over previous versions. It includes expanded coverage of multivariate analysis, increased emphasis on effect sizes and confidence intervals, updated examples and datasets, and improved clarity and organization. Whether you're a student, researcher, or professional, this book will provide you with the knowledge and skills you need to master statistical analysis using SPSS.
Tips for Getting the Most Out of the Book
Okay, so you've got your hands on Discovering Statistics Using IBM SPSS Statistics (2013). Awesome! But how do you make sure you're really getting the most bang for your buck? Here are a few tips to maximize your learning and statistical prowess.
First and foremost, don't just read the book passively. Statistics isn't a spectator sport; it's something you need to actively engage with. Work through the examples, try the exercises, and don't be afraid to get your hands dirty with the data. The more you practice, the better you'll understand the concepts.
Take advantage of the online resources. Andy Field's website is a goldmine of additional materials, including datasets, practice quizzes, and video tutorials. These resources can help you reinforce your learning and identify areas where you need more practice. Plus, the video tutorials can be especially helpful if you're struggling with a particular concept.

If you're stuck on a problem or don't understand a concept, don't hesitate to ask for help from your instructor, classmates, or online forums. There are plenty of people who are willing to help you succeed.
Focus on understanding the underlying concepts, not just memorizing formulas. It's tempting to try to memorize all the formulas and procedures, but that's not the best way to learn statistics. Instead, focus on understanding the logic behind the formulas and why certain procedures are used. This will help you apply your knowledge to new situations and solve problems more effectively.
Use SPSS regularly. The more you use SPSS, the more comfortable you'll become with it. Try to find opportunities to use SPSS in your own research or work. This will help you develop your skills and build your confidence. Plus, it's a great way to impress your boss or professor.
Read widely. Discovering Statistics Using IBM SPSS Statistics is a great starting point, but it's not the only resource you should use. Read other statistics books, articles, and websites to broaden your knowledge and get different perspectives. The more you read, the better you'll understand the field of statistics.
By following these tips, you can get the most out of Discovering Statistics Using IBM SPSS Statistics (2013) and become a statistical whiz in no time. Good luck, and happy analyzing!
