[PVRCNC] More bad SS statistics

[alsopb]

Guys,

To provide an alternate analysis of whether assisted helps or hurts, I
submit the following analysis.

1.  Data set - the most recently published 2002 CW SS results #3
2.  Data included: 
	For assisted-- all stations
	For SO -- all class B stations 
3.  Comparison method:  compute mean and standard deviation
4.  Hypothesis to be tested-- On the average assisted operation
improves scores.

Suffers from the following inadequacies.  No control group
established. Sampling is questionable.  Not all U stations may have
been high power-- thus the affect of power is possibly a confounding
factor.

Results:  SO   mean = 97103 standard deviation 48752  20 data points
               mean =101639 standard deviation 45719  (ignoring the
one 10K outlier)

Results:   SOA  mean = 129218  standard deviation 39816   11 data
points.

Just comparing the means shows a benefit of over 30% for packet.  If
one also considers the standard deviations, one can't conclude
anything.  The distributions are just too scattered.

Note: If one were to include A stations in the SO results, the mean
would have been even lower.
