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 are 3 dots over 4; 2 dots over 5; 4 dots over 6; 1 dot over 7; 4 dots over 8; 3 dots over 9; 4 dots over 10; and 2 dots over 11. There are no dots over 1, 2, 3, 12, or 13.

To identify which dot plot includes an outlier, we need to look for a point that is significantly different from the others. Outliers are often much lower or higher than the other values in a data set.
First Dot Plot: The data points are clustered from 4 to 11, with no values less than 4 or greater than 11. No outlier present.
Second Dot Plot: The data points are clustered from 1 to 7, with a single dot at 13, which is much higher than the rest. This indicates the presence of an outlier.
Third Dot Plot: The data points range from 1 to 8, so no outlier present.
Fourth Dot Plot: The data points are clustered from 1 to 7, with no outliers present.
Based on this analysis, the second dot plot includes an outlier (the dot over 13).
