The Theory Of Sample Surveys And Statistical Decisions - 2nd Fully Revised And Enlarged Edition

In this second edition of the book, has two new chapters (14) Multiple & Partial Correlation Regression and (15) Non-Parametric Methods of significant academic importance have been incorporated. Some numerical examples on Multiple and Partial correlation-regress ion coefficients based on their fundamental definitions have been provided.

In 14th chapter, the process of how to calculate Spearman's rank correlation, partial correlation, multiple correlation coefficient and multiple regression using their fundamental definitions as well as appropriate statistics formula in terms of simple correlation coefficients have been provided.

In 15th Chapter, the data collected in social sciences are usually based on answers provided by respondents through their memories which often suffer due to their memory laps, intentional errors etc. The most appropriate methods (N.D. Methods) to analyse such data are provided. The appropriate empirical studies in both the chapters have been provided to the students and it's words to be familiar easily with the basic and crystal clear concepts of the subject matters.

These examples will be proved to be very significant assets to its readers and users to understand the subject matter very fundamentally.
