Siegel S. Nonparametric statistics for the behavioral sciences

McGraw-Hill, 1956 – 312 p. - In this book the tests presented according to the research design for which each is suited. In discussing each test, the attempt has been made to indicate its "function," i.e., to indicate the sort of data to which it is applicable, to convey some notion of the rationale or proof underlying the test, to explain its computation, to give examples of its application in behavioral scientific research, and to compare the test to its parametric equivalent, if any, and to any nonparametric tests of similar function.
