let x1, x2, x3,....... xn be n values of a variable X. If these values are changed to x1+a, x2+a,.... xn +a, where a belongs to R, show that the variance remains unchanged.

let x₁, x₂, x₃,....... x_nbe n values of a variable X. If these values are changed to x₁+a, x₂+a,.... x_n +a, where a belongs to R, show that the variance remains unchanged.
