Question

calculate standard deviations of the following data 25,50,45,30,70,42,36,58,34,60​

Answer 1

Explanation:

THE CORRECT ANSWER IS 13.38

FORMULA FIR CALCULATING STANDARD DEVIATION IS

σ2 =Σ(xi - μ)2

-----------------

N

(25 - 44.6)2 + ... + (60 - 44.6)2

------------------------------------------

10

=1790.4

---------------

10

= 179.04

= 179.04σ = √179.04

= 179.04σ = √179.04= 13.380582946942
