Consider the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. It is added to each number, the variance of the numbers so obtained is

Consider numbers are 1,2,3,4,5,6,7,8,9,10


If one is added to each number then, numbers will be


Let say xi = 2,3,4,5,6,7,8,9,10,11


So, N= 10



Standard deviation




Hence, the variance is 8.25
