For example, let's say you use Amazon Mechanical Turk for participant recruitment. What if you now also use online message boards? Can you aggregate the data together as long as the procedure for both sets of participants is identical? Could a reviewer reject your work because of this?

    See this: academia.stackexchange.com/help/on-topic, questions about the content of research are off topic. Sorry. – Buffy Jun 20 at 20:34
  • But this is somewhat about "processes of researching"? – Josiah Jun 20 at 20:40

If your question is about the statistical validity of the results of a study using multiple recruitment sources for participants, then there is nothing inherently wrong with aggregating your data per se.

Be aware of course that "recruitment pathway" could be a confounding factor, depending on your study. This is going to be study specific. If your study is testing a new diabetes medication, recruitment pathway is not as important. If your study is looking at introversion and personality types, different recruitment pathways may yield significantly different results.

    @AzorAhai sorry. It will never happen again, sir. But you down vote half of my answers anyway, so I might as well get the +15 for an accepted answer, right? And it helped the OP, so mission accomplished! – Vladhagen Jun 21 at 9:18
  • I'm not sure why you think that I downvote you so much but ok – Azor Ahai Jun 21 at 17:30
