Dear Group Members,
I have statistical problem, concerning
generation statistical sample size from known groups
of the registered patients to be testing parametric and nonparametric
variables of such patients from 3 regions:
There are medical centers from 3 selected regions
Each region have 3 levels (regional, district, basic medical care)
Region I : Regional1 N=2792 --> n=248 acc to Cavalli-Sforza test (alfa=0.05)
District1 N=5062 --> n=463
District2 N=2155 --> n=194
District3 N=1023 --> n=89
Basic1 N=(90-350) --> n=41?
Region II: Regional1 N=1000 --> n=88 acc to Cavalli-Sforza test (alfa=0.05)
District1 N=631 --> n=56
District2 N=1500 --> n=140
District3 N=4000 --> n=362
Basic1 N=115 --> n=34
Region III: Regional1 N=1869 --> n=174 acc to Cavalli-Sforza test (alfa=0.05)
District1 N=2346 --> n=219
District2 N=800 --> n=73
District3 N=796 --> n=72
Basic1 N=(90-350) --> n=22
I should be very appreciated for indicate me test or strategies for
generating minimal sample sizes (n) for statistical purposes.
sincerely
