Returns the average value and the standard deviation
The function \(MeanStDev\) returns the average and standard deviation of the available data. For a sample use \(SMeanStDev \)
The result is a list containing the average value and the standard deviation in this order.
MeanStDev (List) = [average, deviation]
a=[4,6,9,7,9,2,4,6,3]
MeanStDev (a)= 5.56 2.51
