Have an exam in 30min😂

[@theskyblue5351]

How was your exam😅

[@andrewflores5842]

if a resercher is looking for a certain sample such as "women who smoke" is this non-probability? as well since its is a specific group he's looking at would this be convenience sampling, or purposive sampling?

[@EvanOrtlieb1]

That would be a form of purposive sampling...a non random sample

[@ramdev4537]

@@EvanOrtlieb1 If the targeted population is 'women who smoke', then the researcher selects every third woman who is a smoker, then wouldn't this be systematic sampling?

5:06 muestra intencional no probabilística que sí es evidencia válida para fines descriptivos no inferenciales

[@michaelrogebienclanor6167]

Isn't there a snowball sampling in the non probability?

[@EvanOrtlieb1]

Snowball sampling is indeed a form of non probability sampling. It can take on different shapes but is useful to some research.

[@sup3r475]

yea im not passing this exam

[@EvanOrtlieb1]

what part is the most challenging for you?

[@sup3r475]

@@EvanOrtlieb1 a lot lol but I think at this point it is trying to figure out when a non-probability sampling method is warranted in comparison to a probability shampling method. Is the sampling method up to the researchers discretion or are there guidelines to follow

[@EvanOrtlieb1]

I would recommend doing random if possible but most of the time, it isn't feasible. So often times people go w convenience or purposive. It really depends upon the end goal (whether a class assignment, a peer reviewed paper, an industry research project,etc) and whether you seek generalizability across different settings.
