OK
We have a working example now of the standard deviation algorithm. The
working code is now located at
http://www.nylxs.com/docs/workshops/stats.h.cpp.html
for the stat's library
http://www.nylxs.com/docs/workshops/linklist.h.html
the linklist library
http://www.nylxs.com/docs/workshops/test_del.cpp.html
the test program
the relavent output is as follows
10505021 Found first value ==> '99' at node =='0x836b020
10505022 Found next value ==> '99' at node =='0x836b040
10505023 HELLO WORLD
10505024 The mean population occurance for any number is ==> 1000
10505025 The stanard deviation is ==> 33.8308
next is to create or alter the stddev method so that it looks at
a single datapoint, saw the number 7 from a 1000 random selections
between 0-99
do that 1000 times and see what it's specifc bellcurve looks like and
its standard deviation. With perfect randomness, you would expect and
mean of 1/100 * 1000 = 10.
