When using 1-Var Stats on a scientific or graphing calculator, the resulting statistical output includes two values for the standard deviation of the data set. These values are labeled as Sxand σx in the statistical output. Why is it necessary to give two values for the standard deviation? How would you choose which one to use as the standard deviation of a data set you are working with? Be sure to explain the difference between these two values as you answer these questions
