Question

If 20 were added to each of the vlaues in a data set that originally had a standard deviation of 8, the standard deviation of the resulting data would be 28

Answer 1

Answer:

False (I assume it's a true/false question)

Step-by-step explanation:

Standard deviation measures how spread out the data is.  If you add 8 to all the data values, the distribution of data moves to the right (on a graph) 8 units. The shifted data are no more and no less spread out than before.  The standard deviation does not change.
