"The material in this book is based on my several years' experience in construction and evaluation of examinations, first as a member of the Board of Examinations of the University of Chicago, later as director of a war research project developing aptitude and achievement tests for the Bureau of Naval Personnel, and at present as research adviser for the Educational Testing Service. During this time I have become aware of the necessity for a firm grounding in test theory for work in test development. When this book was begun the material on test theory was available in numerous articles scattered through the literature and in books written some time ago, and therefore not presenting recent developments. It seemed desirable to me to bring the technical developments in test theory of the last fifty years together in one readily available source. Although this book is written primarily for those working in test development, it is interesting to note that the techniques presented here are applicable in many fields other than test construction. Many of the difficulties that have been encountered and solved in the testing field also confront workers in other areas, such as measurement of attitudes or opinions, appraisal of personality, and clinical diagnosis. The major part of this book is designed for readers with the following preparation: (1) A knowledge of elementary algebra, including such topics as the binomial expansion, the solution of simultaneous linear equations, and the use of tables of logarithms; (2) Some familiarity with analytical geometry, emphasizing primarily the equation of the straight line, although some use is made of the equations for the circle, ellipse, hyperbola, and parabola; and (3) A knowledge of elementary statistics, including such topics as the computation and interpretation of means, standard deviations, correlations, errors of estimate, and the constants of the equation of the regression line. It is assumed that the students know how to make and to interpret frequency diagrams of various sorts, including the histogram, frequency polygon, normal curve, cumulative frequency curve, and the correlation scatter diagram. Familiarity with tables of the normal curve and with significance tests is also assumed. In textbook fashion, each chapter concludes with problems and exercises"--Preface.
