The mean deviation for n observations x(...

The mean deviation for n observations `x_(1),x_(2)…….x_(n)` from their median M is given by
(i) `sum_(i=1)^(n)(x_(i)-M)`
(ii) `(1)/(n)sum_(i=1)^(n)|x_(i)-M|`
(iii) `(1)/(n)sum_(i=1)^(n)(x_(i)-M)^(2)`
(iv) `(1)/(n)sum_(i=1)^(n)(x_(i)-M)`

A

`sum_(i=1)^(n)(x_(i)-M)`

B

`(1)/(n)sum_(i=1)^(n)|x_(i)-M|`

C

`(1)/(n)sum_(i=1)^(n)(x_(i)-M)^(2)`

D

`(1)/(n)sum_(i=1)^(n)(x_(i)-M)`
