Hi,

Your question:  Recommendations for research methods textbooks?

Kindly see the following books:

For qualitative methods:

Qualitative Research & Evaluation Methods: Integrating Theory and Practice Hardcover

by Michael Quinn Patton  

ISBN-13: 978-1412972123ISBN-10: 1412972124 Edition (Fourth Edition)

Statistics/quantative methods:   Social Research Methods  by  Alan Bryman

For Epidemiology:  An IntroductionPaperback

by Kenneth J. Rothman

For qualitative methods, check out The Ethnographer's Toolkit, editors Jean J. Schensul and Margaret LeCompte

Hi all

Thanks for your suggestions.  I have an old edition of Field's SPSS book and we have been considering the current edition as there seems to be quite a bit more in it.  I've also got Bryman, but again it's about 10 years old so might be ready for an update.  We'll look into the other suggestions too.

Regards

Andrew

from an ecologists' point of view: I love Quinn & Keough: Experimental Design and Data analysis for biologists - should be applicable to your questions as well

A very good general book on research methods is:

Remler, Dahlia K., and Gregg G. Van Ryzin. Research methods in practice: Strategies for description and causation. Sage Publications, 2014.

An a couple of excellent books on statistical methods, in Stata and more generally (albeit, written by economists):

Cameron, Adrian Colin, and Pravin K. Trivedi. Microeconometrics using stata. Vol. 5. College Station, TX: Stata Press, 2009.

Cameron, A., & Trivedi, P. (2005). Microeconomics: Theory and methods. Cambridge: Cambridge University.

Regarding qualitative methods I have found "Qualitative Data Analysis: An Expanded Sourcebook" by Miles and Huberman useful. My experience is from reading the second edition, perhaps there is a more recent version available today.

I find the Rothman's Epidemiology books (Introductory and modern) more illustrative and helpful.

http://www.amazon.ca/Epidemiology-Introduction-Kenneth-J-Rothman/dp/0199754551

I would greatly recommend any of Alan Bryman's research methods textbooks as an introduction.
