Free online inferential statistics textbook that is being offered by Richard Lowry, Professor of Psychology Emeritus, Vassar College. It is part of a large site which offers a number of statistical procedures, calculators and other information.

As Lowry did not provide a preface or other introductory text, I unfortunately can’t tell you much more about this work. It would seem the information is geared for psychology students, rather than mathematics majors simply because Lowry was a member of the Psychology Department at Vassar.
