This ordered stem and leaf plot shows the number of votes received by $12$ students running for student body president.

Stem	Leaf
2	0,2,2,8
3	2
4	2,3,4,5
5	1,4
9	8

Identify the outlier in the data set.

• A. $45$
• B. $54$
• C. $98$

Answer 1

The correct option is C $98$

If we see at the last two rows of the stem and plot data set, we can observe that ${11}^{th}$ student got $54$ votes and ${12}^{th}$ student got 98 votes.

$98$ votes is a large number of votes as compared to $54$ votes and also the difference is large.
$98$ is the outlier.
