To find the median of a set of seven scores ($8$, $4$, $12$, $14$, $3$, $2$, $3$), the scores are rearranged from lowest to highest ($2$, $3$, $3$, $4$, $8$, $12$, $14$), making the middle score $4$. If an even number of scores exists, such as by adding a score of $15$ to the set, there are two scores in the middle of the distribution ($4$ and $8$), and the median is the value halfway between them, which is $6$.
