This book hopes to accomplish for students of statistics what Silvanus Thompson's book Calculus Made Easy, in print since 1910, accomplished for numerous generations of students. His book is prefaced as follows:
The authors of textbooks on mathematics seldom take the trouble to show you how easy the calculations are. They seem to desire to impress you with their tremendous cleverness by going about it in the most difficult way. I present you with the know-how how it is really done.
