To those who have been well trained in mathematics, the acquisition of statistical techniques offer no particular difficulty. To many otherwise capable students, however, either because of inadequate preparation in mathematics, or because their preparation is not very recent, the application of statistical method to data obtained from test and experiment is more than ordinarily difficult. It is for this group of students that this book has been especially written. Its primary purpose is to present the subject in a simple and concise form understandable to those who have no previous knowledge of statistical method. The book, says R. S. Woodworth of Columbia University, "...is the product of genuine teacher' experience, and is exceptionally well adapted to the student's use. To an unusual degree, it succeeds in meeting the student upon his own ground."
