Normal distribution intelligence myth
Webnormal distribution [3]. More subtly, probabilistic models for determining scores based on peer grades often use nor-mal priors over their output [18, 19]. As a result, they will push grade distributions to be normal. The question then remains about whether these distributions should look nor-mal in reality or another prior needs to be found.

(2) In the following, we use K(x;m,s,a) for the CDF of the skew normal distribution. Note that if a = 0, we have a Gaussian distribution of mean m and variance s2. For m = 0 and s = 1, the Figure2shows the role of a in the skew normal distribution.
