Use the image to answer the question.

An illustration shows a number line with arrows on both ends ranging from 1 to 13 in one unit increments. Dots are plotted above the number line to indicate frequency. There is 1 dot over 2; 2 dots over 7; 4 dots over 8; 4 dots over 9; 3 dots over 10; 4 dots over 11; 3 dots over 12; and 2 dots over 13. There are no dots over the numbers 1, 3, 4, 5, and 6.

What number is the outlier in this dot plot?

The outlier in the given dot plot is the number 2, as it has only 1 dot while other numbers have higher frequencies, particularly numbers like 8, 9, 11, which each have multiple dots. This makes 2 stand out as significantly lower than the other frequencies.
