think makes sampling so difficult, in the case, for instance, of how
often advocacy actions should be proposed?
Well, as a simple issue of weighting, should geographic weighting be
applied based on size of a given language speaking population? e.g.
Should the sample of English speaking respondents from India be relevant
to the region's weight in English as a language, it's population as a
portion of humanity, its estimated online population, or some other
global-relative weighting?
Or how about projects: are all project populations to be the same size?
I'd be very interested in what field you are a professional
statistician; my area is health sciences, particularly public health.
