Answer:
5
Explanation:
This is actually a little laughable to me, not because that you don't understand, but that the entire data set is just 5.
"The center of data is a single number that summarizes the entire data set. It is important to use the correct method for finding the center of data so you can accurately summarize the data set. You can do this by using either the mean or the median."
Of course, you don't need any fancy calculations, because there is only one number: 5.
So, the center of the data is going to be 5. A lot of a aspects of that data set are going to be 5, actually.
