As others already posted about the Statistical theoretic aspects of it,
I want to add that weights of people are not normal distributed due
There is a minimum weight an individual below no one can surpass; same
Also the probabilities for symmetrical z scores are not the same, etc.
This lead researchers in the area of anthropometrics to create
transformations on these distributions in order to be able to use test
we're are used to with normal distributions.
See for an example: http://www.jstor.org/pss/2982992.
