For those seeking an introductory statistics book with a degree of rigor, several options are discussed. "The Practice of Statistics" is commonly used in academic settings but is noted for lacking rigor. "Mathematical Statistics with Applications" by Wackerly, Mendenhall, and Scheaffer is mentioned as a solid choice, though opinions on its rigor vary. The "Head First Statistics" book is recommended for its engaging style and supplemental material, despite its unconventional presentation. However, it may not meet the needs of those looking for extensive mathematical proofs. It's highlighted that many rigorous statistics texts assume familiarity with advanced calculus or mathematical analysis, making them less suitable for complete beginners. "Introduction to Mathematical Statistics" by Hogg and Craig is also referenced, particularly for its application-focused approach, though it may not satisfy those seeking a formal treatment of probability theory. Overall, the discussion emphasizes the balance between accessibility and rigor in introductory statistics texts.
