# The measure which takes into account all the data item is

$\begin {array} {1 1} (A)\;Mean & \quad (B)\;Median \\ (C)\;Mode & \quad (D)\;None \: of \: these \end {array}$

We have Mean = $\large\frac{Sum \: of \: all\; observations }{Number \: of \: observations}$
Thus mean is the measure of each item.
