Mean = add all numbers together and divide by the number of values;
34+24+35+33+29+47+55=257/7=36.72=37
S.D.= each number minus the mean squared;
34-37=-3%5E2=9
24-37=-13%5E2=169
35-37=-2%5E2=4
33-37=-4%5E2=16
29-37=-8%5E2=64
47-37=10%5E2=100
55-37=18%5E2=324
-----------------------
add them all together = 686=S.D.
