cc wrong about standard deviations and linear trend lines

[Snit]

Being posted to act as a nice summary to point back to as cc insists he is
right... all the evidence needed to prove cc wrong.

About his claims dealing with standard deviations:

cc:
-----
I have to show you how to take an average and standard
deviation?
-----
It's area under the curve, not distance from center you
idiot. Jesus Christ, give up now.
-----
It is not distance from the mean. Repeat: it is not
distance from the mean.

As noted: cc has no leg to stand on. He is simply wrong. This is also true
of his claims about the linear trend line and how Excel and Numbers both
screw up in how they calculate it (yes, I know, he also back pedalled on
that and claimed they do it fine, but then insisted the results they show
are wrong... and make up stories about how I missed some step in those
programs... even though I proved I did not).

Yes, complete proof that the linear trend line was moving up... with both
the data I first used (12 months) and the data cc asked me to use (24
months) using the same linear trend line.

cc's response: just to keep saying I am wrong... but never to offer a shred
of support. And he has none. Bottom line: cc is simply ignorant and
dishonest and unable to admit when he is wrong.
