Question

Calculate the Co-effieient of variation if
N = 5,
x= 3,
Σ Χ2 = 10,
x = 0​

Answer 1

Explanation:-

n = 10, x = 12 and xi2 = 1530 standard deviation = S = √[{(∑xi2)/n} – {(∑xi)/n}2] = √[{(1530)/10} – 144] = 3 coefficient of variation = [(standard deviation)/(mean)] = (3/12) = (1/4) ∴ % coefficient of variation = (1/4) × 100 = 25%.Read more on Sarthaks.com - https://www.sarthaks.com/318000/if-n-10-x-12-and-xi-2-1530-the-value-of-coefficient-of-variation-is-a-25
