Data in the real world can be dynamic and sometimes messy. This complexity might intimidate students who are new to math and statistics, but it's also what makes statistics so interesting! Introductory Statistics: Exploring the World Through Data teaches you how to explore and analyze real data to answer real-world problems. Crafted by authors who are active in the classroom and in the statistics education community, the 3rd Edition pairs a clear, conversational writing style with new and frequent opportunities to apply statistical thinking. Its tone and learning aids are designed to equip all students to analyze, interpret and tell a story about modern data, regardless of mathematical background.
