How do you do standard deviation on a Casio fx115ES???? Help!

re: single variable statistics - if I simply enter three data points (5,10,15) in 'data' and then enter 'var' to see 'n', x-bar, etc., I get nothing back - it doesn't seem to have 'read' my data or done any calculation. Is there some other procedure you have to go through so the calculator knows your through entering data then 'crunch' the numbers?
