well, getting the first boot ... to do the strapping ... might be ... but,
after that ... then REsampling from the first SAMPLE (boot) ... would be a
better way to describe it
similarly ... let's say we do a two stage survey project ... where the
first phase is to circulate a survey form to n=1000 folks (from a large
population) ... and after we get back their responses (let's assume for
fantasy sake that we get all 1000 back) ... we pick n=25 from that 1000 to
do extensive follow up interviews with ... can we assume that the n=25
sample is a SRS of n=25 from the larger population? i don't think so
