You can put this solution on YOUR website! if you have a SD of 35, and you multiply the data set by a factor of 86, what would the new SD be? please help to solve I need a formula.
-------
Ans: 85*35 = 3010
--------------------
Why?
Compare the sd of 1,2,3,4 to the sd of 3,6,8,12
----
The latter sd is 3 times the sd of the former.
