Tentukan simpagan baku dari 3,5,4,7,8,3

Rata-rata = (3 + 5 + 4 + 7 + 8 + 3) / 6 = 30 / 6 = 5 
S = √[tex] \frac{( 3-5) ^{2} + (5 - 5)^{2}+ (4-5) ^{2} +(7-5)^{2}+(8-5) ^{2} +(3-5) ^{2} }{6} [/tex]
= √[tex] \frac{4 + 0 + 1 + 4 + 9 + 4}{6} [/tex]
= √[tex] \frac{22}{6} [/tex]
= √[tex] \frac{11}{3} [/tex]
