For courses in Statistics. This introduction to statistics presents balanced coverage of both the theory and application of statistics and at the same time helps students develop and enhance their critical thinking skills. It shows students how to analyze data that appear in situations in the world around them and features an abundance of examples and exercises--nearly all based on current, real-world applications pulled from journals, magazines, news articles, and more
