Dragons, I see you don't believe in the law of the excluded middle.:-)

Statistics can prove anything: About 30% of traffic accidents are caused by drunk drivers. Therefore 60% of accidents are caused by sober drivers. Therefore it's safer to drive drunk than sober!!!

Hello Jeff; Mathematically, you just summed up the entire article by Bill Schweber with three equations.

Take the fraction 0/0 (zero over zero). Using extrapolation this is equal to 0, 1 or infinity. 0/3 = 0/2 = 0/1 = 0 therefore 0/0 = 0 3/3 = 2/2 = 1/1 = 1 therefore 0/0 = 1 3/0 = 2/0 = 1/0 = infinity therefore 0/0 = infinity With the ability to skew the numbers like this, I think I missed my calling as a marketer (or politician)

Who was it who said "There are Lies, Damned Lies, and Statistics"? (Just googled, Mark Twain popularised it but attributed it to Benjamin Disraeli, but that's doubtful....) Very applicable here though, bad statistics and bad extrapolations are closely related. At this rate, nothing we read in a couple of years time will be able to be believed.... :-)

At this rate, statistically inaccuracies will totally overwhelm us and swamp us fifty feet deep under discarded AOL CD's in less that twenty-leben years!

i love that innumeracy book! i've been using that on all my Lit Major friends for decades! i agree with this article thoroughly, but i do want to make sure we remember the miracle of quasi-math laws: moore's law. that thing is the one and only legitimate one, and it's been in effect for nearly 40 years, though we may be finally coming to the end of it (how many times has that been said about moore's law??).

What quasi-mathematical statements turn me off? Predictions about lost productivity (usually in the $millions or $billions) because of some sporting or other event that will distract workers.

Thats why we have supercomputers calculating system dynamics for critical projects like nuclear energy, space vehicles and global economy. No trending there.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
