Indeed, and that's why I propose that... Shannow Send a noteboard - 18/12/2009 10:31:23 PM
Bell curves are usually not centered on the mean or median. This is a statistical fact.

In order for a distribution to be a bell curve it is, by definition, centered on its mean.

From The Wikipedia article "Normal distribution"
In probability theory and statistics, the normal distribution or Gaussian distribution is a continuous probability distribution that describes data that cluster around the mean. The graph of the associated probability density function is bell-shaped, with a peak at the mean, and is known as the Gaussian function or bell curve.


I propose that the Bell Curve is cut by zero at around 2 standard deviations below the mean. In other words, while it is a perfect Bell Curve, you'd have to draw the bottom portion of it as an imaginary curve below zero strength.

If not that, then it must be a relative scale, where each movement away from the mean is a proportional one, rather than an absolute one.

Remember, RJ's 21 level scale isn't supposed to be superimposed on the Bell Curve. The Bell Curve is merely another, independent tool to represent the channeling population.

The One Power Bell Curve: Proof that it is not centered on 50% of the strongest channeler's strength Shannow - 18/12/2009 08:37:55 AM 1392 Views
I always thought the curve was one sided Asha'man Warder - 18/12/2009 01:17:32 PM 796 Views
The Curve only refers to the channeling population, not to non-channelers. Shannow - 18/12/2009 01:56:25 PM 799 Views
I would say that your sample is flawed. RugbyPlayingAshaman - 18/12/2009 05:02:02 PM 873 Views

But, it sort of does. RugbyPlayingAshaman - 18/12/2009 10:43:08 PM 787 Views
So you're saying that no modern Aes Sedai are even of average strength? Shannow - 18/12/2009 10:51:01 PM 869 Views

So, Aviendha trumps RJ? A woman who, as late as tGS, doesn't know what she's doing with the OP? fionwe1987 - 19/12/2009 06:12:42 PM 783 Views

So RJ used two separate scales, one actual one relative, to explain the same thing? fionwe1987 - 18/12/2009 11:33:20 PM 722 Views
Yes, "Bell Curve" does not mean Gausian. Or normal distribution. amirebram - 19/12/2009 11:24:10 PM 747 Views

That's because outliers in IQ tests are excluded form the curve. *NM* fionwe1987 - 18/12/2009 11:31:23 PM 437 Views
Really?!?! then what is the definition of a IQ of 200? amirebram - 19/12/2009 11:28:18 PM 1060 Views
You can have IQ's above that... fionwe1987 - 20/12/2009 05:09:44 AM 770 Views
I said that in the other post and was half torn to pieces *NM* Sidious - 19/12/2009 11:38:25 AM 378 Views
