A negative Z score does not necessarily indicate anemia. It would have to be significantly low, P < .05, Z < -1.96, to be considered anemic.

math
First of all, the range is not a measure of central tendency. The mean acts as a fulcrum (balance point) for the distribution, therefore outliers on one side will draw the mean out to that side. In other words, the distribution is significantly skewed. In a skewed distribution...
