Final answer:
The dot plot represents the set of data {1, 3, 4, 5, 6}. It shows a dot for each data point, with one dot for each value in the data set.
Step-by-step explanation:
The dot plot represents the set of data {1, 3, 4, 5, 6}. The dot plot shows a dot for each data point, and the position of the dot on the number line indicates the frequency of that value. Since there is only 1 dot for each value in the data set, it represents a set of distinct values.
