You are squaring the wrong numbers.
]]>22 ^ 2 = 484
5 ^ 2 = 25
17 ^ 2 = 289
27 ^ 2 = 729
59 ^ 2 = 3481
Please check that.

Okay, so I'll start from showing you some examples of the standard deviation, and not gonna teach you, but I just want you to correct me in case of my mistakes in calculation.
Note: I will use the whole population for these examples.
1. 62, 35, 17, 27 and 59
62+35+17+27+59
97+44+59
103+97
200
200 / 5 = 40
62 - 40 = 22
35 - 40 = -5
17 - 40 = -23
27 - 40 = -13
59 - 40 = 19
22 ^ 2 = 484
5 ^ 2 = 25
17 ^ 2 = 289
27 ^ 2 = 729
59 ^ 2 = 3481
484+25+289+729+3481
509+1018+3481
4499+509
5008
5008 / 5 = 1,001.6 ~ 1,002
(sqrt)1,002 = 31.65 ~ 32
