Following table shows the points of each player scored in four games:
Player | Game 1 | Game 2 | Game 3 | Game 4 |
A | 14 | 16 | 10 | 10 |
B | 0 | 8 | 6 | 4 |
C | 8 | 11 | Did not play | 13 |
(ii) To find the mean number of points per game for C
(i) Average number of points scored per game by A$=\frac{Total\ points\ scored\ by\ A\ in\ all\ games}{Number\ of\ games\ played\ by\ A}$
$=\frac{14+16+10+10}{4}=\frac{50}{4}$ $=12.5$
(ii) Average number of points scored$=\frac{Total\ points\ scored\ by\ a\ player\ \ in\ all\ games}{Number\ of\ games\ played\ by\ the\ player}$
C played only 3 games.
Therefore,
We have to divide by 3 not 4.
Average number of points scored per game by C$=\frac{Total\ points\ scored\ by\ C\ in\ all\ games}{Number\ of\ games\ played\ by\ C}$
$=\frac{8+11+13}{3}=\frac{32}{3}$ $=10.33...$
(iii) Average number of points scored per game by B$=\frac{Total\ points\ scored\ by\ B\ in\ all\ games}{Number\ of\ games\ played\ by\ B}$
$=\frac{0+8+6+4}{4}=\frac{18}{4}$
$=4.5$
(iv) Comparing the mean points scored by A, B and C,
Mean points scored by A is the highest.
Therefore, A is the best performer.
