Statistics: Unlocking the Power of Data, 2nd Edition continues to utilize the intuitive methods like randomization and bootstrap intervals to introduce the fundamental idea of statistical inference. These methods are brought to life through authentically relevant examples, enabled through easy to use statistical software, and are accessible at very early stages of a course. The program includes the more traditional methods like t-tests, chi-square texts, etc. but only after you have developed a strong intuitive understanding of inference through randomization methods. The focus throughout is on data analysis and the primary goal is to enable you to effectively collect data, analyze data, and interpret conclusions drawn from data. The program is driven by real data and real applications.
