[CQ-Contest] Survey results

[W0uo at cs.com]

   The accuracy of a survey depends on four things.  First, the size of the 
sample (not the proportion of the population sampled). Second, the randomness 
of the sample.  Third, the response rate (to be sure the respondents are not 
self-selected) and, finally, the construction of the questions.  

    Most professional firms are quite good at controlling these factors and 
will provide the information you need to evaluate the surveys.  I'm sure an 
inquiry to the league will produce the additonal information you need.
