Question

The table shows the points of each player scored in four games.

Players	Game I	Game II	Game III	Game IV
X	14	16	10	10
Y	0	8	6	4
Z	8	11	Did not play	13

$Y$ played in all the four games, how would you find mean?

Answer 1

$Y^{\prime }$s points

Game $I=0,$ Game $II-8$

Game $III=6$, Game$IV-4$

$Y^{\prime }smean=\frac{sumofobservation}{No.ofobservation}$

$=\frac{0+8+6+4}{4}=\frac{18}{4}=4.5$

$\therefore$ The mean of $Y=4.5$
