Question

Medals won by the U.S. in Winter Math Olympics are as follows:


Identify the outlier corresponding to the number of medals won in different years.

• A. $26$
• B. $9$
• C. $23$
• D. $24$

Answer 1

The correct option is B $9$

The given data regarding the number of medals won by the U.S in the Winter Math Olympics in different years are as follows:


All the numbers of medals in the above table are between $20$ and $30$ except the number of medals won in the year $2006$.

In $2006$, U.S. won $09$ medals in Winter Math Olympics.

$\underset{–}{\text{Oulier:}}$ A value in a data set that is very different from all the other values of the data set.

As $9$ is very different from the remaining data points $\{26,24,23,26\}$, the outlier of the given data set is $9$.
