Answer:
A B C
Explanation:
The histogram in choice A, the box plot in choice B, and the dot plot in choice C are all correct answers.
The median of the set is 7, and the quartiles are at 4 and 14, which the boxplot shows. The histogram and dotplot show the correct values, although I'd say the boxplot is better for a quick glance to see the median and IQR easily.
