#### LibraryThing Review

User Review - DarkWater - LibraryThingThe book is honestly a great introduction to statistics, especially for psychology! Unfortunately, it is FULL of mathematical errors, especially in formulas, solutions to selected problems, and examples within the chapters. For a third edition, this seems pretty unacceptable.
