"The book does an admirable job of achieving the logic and arithmetic of probability without sacrificing rigor and while still retaining a readable and enjoyable writing style. For the most part, this little book is a gem that would serve well as a supplement to many standard statistical methods courses. . . .I found Lowry's book to be delightful reading and of benefit to both graduate and undergraduate statistics students as well as liberal arts students." --Journal of the American Statistical Association
