Thank you Mehul and Saker for your answers.

I would recommend 'Sample survey methods and theory' by Morris H. Hansen, William N. Hurwitz, William G. Madow, especially volume 1 for those who start doing it.

Oualid, you haven't made it very clear what you are looking for. For an introductory text, I would look to Floyd J. Fowler, Survey Research Methods, latest edition is 2008. A classic just on sampling is Leslie Kish, Survey Sampling (1995). These are common books, so they should be easy to get. Amazon.de has both.

That's a pretty wide set of books. For a quick sampling review, Kalton's little green Sage book is great. I still love Kish (some of my colleagues don't), and Lohr's textbook is really well-designed and easy to understand. If you want survey research design and methodology more broadly, I'd second Fowler for a general overview of survey research and some how-to (but not for sampling). Groves et al (2007) "Survey Methodology" is probably the best soup-to-nuts overview, but not a how-to book.

Thank you Lyubov, Robert and Matt. I finally decided to start with "Survey Methodology" of Groves et al and "Sampling: Design and Analysis" of Sharon Lohr.

hii.....

There are various books for sampling and design of experiment.Initially you could start with

1)Sampling Techniques by W.G. Cochran

2) Theory and methods of survey Sampling by Parimal Mukhopadhyay

3)Sampling theory by Desraj and Promod Chandhok

4) Sampling Theory of Surveys with Applications by P.V Sukhatme, B.V. Sukhatme and Ashok C.

5) Experimental Design by Cochran and Cox

6)Design and Analysis of Experiments by Montgomery, D.C.

7)Fundamentals of Applied Statistics by Gupta, S.C. and Kapoor, V.K. (this book is very elementary and easy to understand)

I hope these books will be helpful for you.

What is the  best of the ( downloadable) books on sampling techniques ?
