Practical Statistics for the Physical Sciences
S
tatistical proce dures can make an important con tribution to evaluating scientific research. Now you can get a better understanding of how to use and apply these proce dures to obtain the maxi mum amount of information from your data. Η ^ Β Η Η Η Κ Ι Μ Β Ι Η Κ With this dynamic new "how-to" book, you'll learn the concepts underly ing the use of statistics through understandable, easy-to-follow steps. You'll cover the basic principles and assumptions required for using sta tistical analyses. Then you'll learn how to select and apply statistical tech niques—and to properly interpret your results. A comprehensive reference, this book includes worked-out examples illus trating each procedure. Plus, commonly used formulas have been printed on the inside covers and a separate colored section of statistical tables has been included for easy reference. Practical Statistics for the Physical Sciences offers a useful and practical approach to working with and understanding statistical procedures. No prior knowledge of statistics is necessary, and only a basic knowledge of mathematics and algebra is required. Larry L. Havlicek, University of Kansas Ronald D.
