Statement-1 : The variance of the variates 112, 116, 120,125,132 about their A.M. is 48.8. Statement-2 : sigma=sqrt((Sigma_(i=1)^(n) f_i(x_i-barx)^2)/(Sigma_(i=1)^(n) f_i)

Statement-1 : The mean deviation of the numbers 3,4,5,6,7 is 1.2 Statement-2 : Mean deviation = (Sigma_(i=1)^(n) |x_i-barx|)/n .

Let S_(k)=underset(ntooo)limunderset(i=0)overset(n)sum(1)/((k+1)^(i))." Then "underset(k=1)overset(n)sumkS_(k) equals

The standard deviation (sigma) of variate x is the square root of the A.M. of the squares of all deviations of x from the A.M. observations. If x_i//f_i , i=1,2,… n is a frequency distribution then sigma=sqrt(1/N Sigma_(i=1)^(n) f_i(x_i-barx)^2), N=Sigma_(i=1)^(n) f_i and variance is the square of standard deviation. Coefficient of dispersion is sigma/x and coefficient of variation is sigma/x xx 100 The standard deviation for the set of numbers 1,4,5,7,8 is 2.45 then coefficient of dispersion is

The standard deviation (sigma) of variate x is the square root of the A.M. of the squares of all deviations of x from the A.M. observations. If x_i//f_i , i=1,2,… n is a frequency distribution then sigma=sqrt(1/N Sigma_(i=1)^(n) f_i(x_i-barx)^2), N=Sigma_(i=1)^(n) f_i and variance is the square of standard deviation. Coefficient of dispersion is sigma/x and coefficient of variation is sigma/x xx 100 For a given distribution of marks mean is 35.16 and its standard deviation is 19.76 then coefficient of variation is
