Are there standard example research papers for teaching methodology and experiments?
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/
