But not all, and as was pointed out previously, how could a sample of 

the

population be more accurate than the entire population?

Jack,



Because the QUALITY of data is much better.  As Smith and others have 

shown.  If you want to use ecologic or aggregate data, at least pick 

a state that has the most aggregates in the nation like Iowa.  There 

is 1% of the population there with 99 counties.  It has a SEER 

Registry and the highest radon in the U.S.  This is quality 

information.  The higher the quality information, the less you see 

Cohen's inverse association.
