Statistics for research - Shirley Dowdy - książka wyd. 1983

Opis

For students in both the natural and social sciences with no prior knowledge of statistical methods. It provides not only an understanding of the concepts of statistical inference but also the methodology for the most commonly used analytical procedures. Stressing practicality throughout, the text avoids excessively theoretical proofs and offers details of mathematical techniques only as they are needed. The exposition includes a wealth of examples, many based on actual research situations. Updated for this edition, it also includes considerable computer output of the widely used SAS System for the statistical procedures discussed
