Question

Compute Standard Deviation of the data 19, 23, 16, 07, 18, 35, 14, 24

Answer 1

As we know we are given so we can easily find

∑x = 19+23+16+07+18+35+14+24 = 156 
n = 8 
so here ∑x^2 = 19^2+23^2+16^2+7^2+18^2+35^2+14^2+24^2 =3516 

as we know about the Variance = (∑x^2 - ( ∑ x)^2 / n ) / (n-1) 
putting the values in the formula so Variance = (3516 - (156)^2 / 8) / 7 
Variance = 474/7 
Variance = 67.7143 

we can find Standard deviation  with this formula Standard deviation = sqrt (variance) 
putting the values of variance in it .Standard deviation = sqrt (67.7143) 
so Standard deviation will be  = 8.2289
