<DIV><STRONG><FONT color=#0000ff face=Arial>Bob.. It is not so much
that people don't have a solid understanding of STATISTICAL ANALYSIS as
much as the problem of it happens more often than some are willing to admit or
realize that a judge that award a zero can be the only one that was the accurate
judge. The assumption being that if only one judge gave a zero then the rest
must be correct and the lone wolf is the wrong one. History has shown that
repeatedly is not the case in actuality. Speaking from my own personal
experience when judging both in Canada and the U.S. ~ yes `~ even at
the Nats.. Shudder..!!! </FONT></STRONG></DIV>

<DIV><SPAN>The only statistically valid comparison is when a large enough
number of judges are judging the same flight. Most local contests have
only two judges per flight. There is no way to know if one judge is
doing a better job than the other because you don't have a large enough group
to establish an average score.</SPAN></DIV>
<DIV><SPAN></SPAN> </DIV>
<DIV><SPAN>The only thing you may see are "high" and "low" judges, but that is
not important unless there is bias, which falls into my first statement.
</SPAN></DIV>
<DIV><SPAN></SPAN> </DIV>
<DIV><SPAN>The NATS comes close to having large enough judging groups<VAR
id=yiv708315470yui-ie-cursor></VAR>. But, at least up until now, no one
has been willing to propose using any statisical analysis on the judges
performance. </SPAN></DIV>
<DIV><SPAN></SPAN> </DIV>
<DIV><SPAN>The Worlds uses TBL to analyze judging performance and exclude
"bad" scores. It is contriversial, since most people don't have a solid
understanding of the statistical analysis used. The raw scores are
posted during the preliminaries, and everyone uses those to determine
placement. But when TBL is applied, it can alter the pilot positions by
tossing out scores that are ruled statistically invalid.

<DIV>Doesn't having a scoring system that allows for aggregated data analysis
help with judging the judges over time?</DIV>
