I would love for you to be right, because it would solve all our problems, but 0 is the challenge... Shannow Send a noteboard - 29/10/2012 07:56:34 PM
In any case, for those who aren’t aware, this thread is based on RJ’s statement that channeler strength in WoT can be represented by a Bell Curve distribution. For those unfamiliar with statistics, a Bell Curve is a perfectly normal distribution, peaking at the average and petering off to either side in a perfectly symmetrical manner.

A Bell Curve by definition means that the distance from the weakest to the strongest channeler is intersected at exactly the 50% mark by the mean (the average channeler). Any skewing of the distribution would mean that the term “Bell Curve” cannot be applied to the distribution. Instead, it would then be either a positively or negatively skewed distribution. But not a Bell Curve.

So the basic rule is that the average channeler has to be exactly half as strong as the strongest channeler. Or to put it differently, a channeler x standard deviations away from the mean on the weak side, must be exactly as far from the mean as a channeler x standard deviations away on the strong side.


And I don't really want to draw any conclusions about the channeling population, but your logic is completely off.

A simple illustration: Any normal distribution is a bell curve, regardless of its standard deviation. So take a normal distribution with a mean of 1 and a standard deviation of 4.1. That means that 9 lies within two standard deviations of the mean, and 1 clearly isn't 50% of 9.


I like what you're saying, and have considered it before as a potential solution, but my problem is that you don't get negative strength in the One Power. Hence, if 1 is the mean, as in your example, and if 4.1 is the standard deviation, how do you get to 1 standard deviation below the mean? Not to mention 2 or 3 standard deviations below the mean?

Because you almost immediately hit zero strength in the Power.

Hence my view that if it's a true Bell Curve, then the lower end of the distribution can not approach zero, since we are talking about the channeler population here, not the total human population. And even the weakest channeler (which is Morgase) has a strength greater than zero.
