Standard deviation is a measure of the overall distribution of your data 
set.  Roughly speaking, it is the mean of the squares of the differences 
between individual data values and the mean data value.  

There is no such thing as "standard deviation on each result". What is it 
you actually want for each result? 

Do you want it's variance from the mean expressed as a multipe of "one 
standard deviation for the dataset" ?
