We warn students about pitfalls in clear cautionary discussions. Simple principles guide the analysis: always plot your data look for overall patterns and deviations from them when looking at the overall pattern of a distribution for one variable, consider shape, center, and spread for relationships between two variables, consider form, direction, and strength always ask whether a relationship between variables is influenced by other variables lurking in the background. We emphasize systematic ways of thinking about data. IPS presents data analysis as more than a collection of techniques for exploring data.IPS has a logical overall progression, so data production and data analysis are a major focus, and inference is treated as a tool that helps us draw conclusions from data in an appropriate way.We focus on the production and analysis of data as well as the traditional topics of probability and inference. IPS examines the nature of modern statistical practice at a level suitable for beginners.IPS has been successful for several reasons:
In IPS, we combine attention to basic statistical concepts with a comprehensive presentation of the elementary statistical methods that students will find useful in their work. After completing a course based on our text, we would like students to be able to think objectively about conclusions drawn from data and use statistical methods in their own work. IPS is elementary in mathematical level but conceptually rich in statistical ideas. We present methods of basic statistics in a way that emphasizes working with data and mastering statistical reasoning. Introduction to the Practice of Statistics (IPS) is an introductory text based on this principle.
