Emily, Zeke, Harry, and Brook each conducted surveys on the number of books people have in their homes. Then, each student determined the accuracy of the following statement.
All measures of central tendency must appear as a number in the set of data collected.
Which student’s statement is CORRECT?
A.
Zeke says this is never true because all the measures of central tendency are never numbers in the set of data.

B.
Emily says this is always true because all the measures of central tendency also have to be numbers in the set of data.

C.
Harry says this is sometimes true because the mean and median may or may not be in the set of data, but the mode is always in the set of data.

D.
Brook says this is sometimes true because the mean and mode may or may not be in the set of data, but the median is always in the set of data.
