The mode

The mode of a set of information is the value that appears with a major frequency.

A dice is thrown ten times and the results are the following:

$$1, 3, 2, 5, 4, 2, 6, 2, 3, 6$$

The table of absolute frequencies is:

Result of the dice Absolute frequency
$1$ $1$
$2$ $3$
$3$ $2$
$4$ $1$
$5$ $1$
$6$ $2$

It is easy to see that the mode is $2$, for it is the most frequent result.

The statistics of the players of Los Angeles Lakers in the first match of the finals of the NBA are the following:

a) What is the mode of scored points (PTS) among the Lakers players?

We can see in the last column, the points column, the only value that recurs is 3 points (those scored by S. Brown and S. Vujacic). And so, the mode is $3$.

b) And the mode of personal fouls (PF)?

The relative table of the number of personal fouls is:

Personal fouls Absolute frequency
$0$ $1$
$1$ $2$
$2$ $2$
$3$ $2$
$4$ $2$
$5$ $1$

We can see that the values $1, 2, 3$ and $4$ recur twice, that is, two players made $1$ foul, $2$ made $2$ fouls, etc. And so, the mode of the personal fouls is $1, 2, 3$ and $4$.
