Question

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.

Answer 1

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 too large.
$\therefore 98$ is the outlier.
