Default Help!!sampling techniques biostats!

hey guys, just completed NBME 13..and came across a question regarding sequential sampling..and this is not listed in Kaplan or FA....which worries me!

How in-depth should my knowledge be for BIOSTATS? far beyond the scope of FA and Kaplan?
exam in t- minus a few weeks

i think it was sequential based... i gathered this from reading a bunch of other forums.

from what i understand sequential is non- probability sampling, and the group of interest/study is chosen within a certain time interval ( perhaps because the census was from 2000)? Also, with this sampling, the researcher has the freedom to further investigate the risks/outcomes by using another group...

but population based would make sense...
can you clarify why?

Thanks in advance

Well the sad part about offline nbmes is that u can to check several sites to know the right answer. Not all write the correct answer.
I have the form online and I'm pretty sure I got population based right. Bcoz census is representative of the population .recheck it once

yes, you're correct, its population-based sampling..and logically, that makes sense. Thanks. I did the NBME online, and my answer choice was incorrect..so i was frantically searching for the right answer.
