(25 + 38 + 42 + 38 + 30 + 43) / 6 = 216/6 = 36
then subtract the mean (36) from every data point, and square it
25 - 36 = -11...-11^2 = 121
38 - 36 = 22^2 = 4
42 - 36 = 66^2 = 36
38 - 36 = 22^2 = 4
30 - 36 = -6...-6^2 = 36
43 - 36 = 77^2 = 49
now find the mean (average) of those numbers
(121 + 4 + 36 + 4 + 36 + 49) / 6 = 250/6 = 41.66
to find the standard deviation, we take the square root of that...
sqrt 41.66 = 6.45
so the standard deviation is 6.45 <
