4 characteristics:
1. “bell shaped” symmetrical
2. Mean = median = mode
3. Asymptotic  no outliers
4. Probabilities or proportion of the area under the curve is add to 1
(=100%)

Area under the curve = % observations / cases / probability
 Standard deviation

SD  Z-score = average distance to the mean

Transformation formula
Any normal distribution (with any mean and standards deviation combination)
can be transformed into the standardized normal distribution  Z-Table. With
the transformation formula you convert a normal variable X to a standardized
normal variable Z.

Z= +1.00, area between the mean and the Z-score is 34,13%. The exact area
underneath the curve that is contained between the z-score and the mean.
