Are there standard example research papers for teaching methodology and experiments? Are there recommended or standard published papers (not books) that show great research methodology/ scientific methods?  I am trying to help out a friend who is in business and they are trying to study aspects of humans (in terms of their clients).  I gave him the book The Craft of Research, but it's long and I wonder if there is a paper that could do the same job.  Basically I want to show him a good example of coming up with a hypothesis, accounting for variables (such as stating that something was done in order to eliminate a problem), and analyzing the results.
Qulatrics has a nice concise (and free) guide to doing marketing research. Not a journal article, but I give it to my students in my research methods course because it's practical and comprehensive but not overwhelming. In fact, they have a lot of useful resources here: http://www.qualtrics.com/university/researchsuite/research-resources/other-resources/ebook-downloads/
