Because standard statistical packages (e.g., SAS, SPSS, SYSTAT) do not account for every possible research situation, the authors have developed a collection of over 400 computer program descriptions written in a user-friendly manner. A Guidebook of Statistical Software for the Social and Behavioral Sciences is the first major reference of statistical software program descriptions along with the information necessary to obtain the programs. Not only do many of the programs mentioned in this volume augment the standard statistical packages, but they are also either free of charge or available for a nominal fee to the user. Furthermore, the computer programs described have been peer reviewed and published in various journals such as Educational and Psychological Measurement, Behavior Research Methods, Instruments & Computers, Computers in Biology and Medicine, Journal of Experimental Education, Behavioral Engineering, Measurement and Evaluation in Counseling and Development, and Teaching of Psychology. Whether you are a quantitative methods expert or a scholar/researcher who is apprehensive about the sophistication of today's statistical methods and computer programs, this book is a must for your reference shelf.
