The project planning document is a basic shell/outline of an empirical quantitative research paper. Your planning document should should have the following sections: (a) Rationale, (b) Objectives; (b.1) General objectives; (b.2) Specific objectives; (c) (Null) hypotheses; (d) Conceptual diagram and explanation of the relationship(s) you plan to test; (e) Measures; (f) Dummy tables/figures; (g) anticipated finding(s) and research contribution(s). Longer descriptions of each of these planning document sections (as well as a few others) can be found [[CommunityData:Planning document|on this wiki page]].

The project planning document is a basic shell/outline of an empirical quantitative research paper. Your planning document should should have the following sections: (a) Rationale, (b) Objectives; (b.1) General objectives; (b.2) Specific objectives; (c) (Null) hypotheses; (d) Conceptual diagram and/or explanation of the relationship you plan to test; (e) Measures; (e) Dummy tables/figures. Descriptions of each of these planning document sections as well as an exemplary example will be available [[TODO-planningdoc|on this wiki page]].
  
I have also provided three example planning documents via our Canvas site:
+
<!---
* [https://canvas.northwestern.edu/files/6908602/download?download_frd=1 One by public health researcher Mika Matsuzaki]. The first planning document I ever saw and still one of the best. It's missing a measures section. It's also focused on a research context that is probably very different from yours, but try not to get bogged down by that and imagine how you might map the structure of the document to your own work.
+
An exemplary planning document from public health researcher Mika Matsuzaki is [https://canvas.northwestern.edu online in Canvas]. Your diagram will likely be much less complicated than Matsuzaki's. Also, please don't be distracted by the fact that Matsuzaki does public health research. You can (and should!) emulate the form rather than the content. You can also check out [http://ajcn.nutrition.org/content/99/6/1450.full the published paper] to see how the project wound up.
* [https://canvas.northwestern.edu/files/6919735/download?download_frd=1 One by Jim Maddock] created as part of a qualifying exam earlier in 2019. Jim doesn't provide dummy tables or anticipated findings/contributions, but he has an especially phenomenal explanation of the conceptual relationships and processes he wants to test.  
+
 
* [https://canvas.northwestern.edu/files/6908606/download?download_frd=1 One provided as an appendix to Gerber and Green's excellent textbook, ''Field Experiments: Design, Analysis, and Interpretation'' (FEDAI)]. It's over-detailed and incredibly long for our purposes, but nevertheless an exemplary approach to planning empirical quantitative research in a careful, intentional way that is worthy of imitation.
+
Please note that the Matsuzaki planning document includes everything except a "Measures" section. Your Measures section should include a two column table where column 1 is the name of each variable in your analysis and column 2 describes the operationalization of each measures and (if necessary) how you will create it.

I do not have strong preferences about the style or formatting guidelines you follow for the paper and its bibliography. However, ''your paper must follow a standard format'' (e.g., [https://cscw.acm.org/2019/submit-papers.html ACM SIGCHI CSCW format] or [https://www.apastyle.org/index APA 6th edition] ([https://templates.office.com/en-us/APA-style-report-6th-edition-TM03982351 Word] and [https://www.overleaf.com/latex/templates/sample-apa-paper/fswjbwygndyq LaTeX] templates)) that is applicable for a peer-reviewed journal or conference proceedings in which you aim to publish the work (they all have formatting or submission guidelines published online and you should follow them). This includes the references. I also strongly recommend that you use reference management software to handle your bibliographic sources.
