Computation of some Basic Parameters

Typical normal distribution parameters are computed using all measurement values (a certain number of single realizations)  

From the ranked series of n measurements of a continuous variable x 

Assume that by atomic absorption spectroscopy of n = 10 samples of sewage water the following concentrations of Zn were found  

Note that the mean does not differ very much from the median. 

Statisticians define skewness and other parameters using the parameters of the distribution. With pj, the so-called/th central moment, skewness is
