The median and standard deviation (S.D.) of a
\( \mathrm{P} \) distribution will be. If each term is increased by 2 :

W
(1) median and S.D. will increased by 2
(2) median will increased by 2 but S.D. will remain same
(3) median will remain same but S.D. will increased by 2
(4) median and S.D. will remain same
