You know where you are comparing the Expected with the observed interval readings to see whether or not there is a skewness in standard deviations.. Where are the expected values derived from? Are there something to do with distribution of standard curve?
E.g.
Interval: (-3,-2) (-2,-1) (0,-1) (0,1) (1,2) (2,3)
Expected: 0.2 1.4 3.4 3.4 1.4 0.2
Observed: 0 0 6 2 2 0
There is an obvious symmetry to the expected values but from where are they derived?
