A librarian was trying to figure out the number of books in the nonfiction section. The values below represent the
numbers of books on each shelf of a corner bookcase
Which measure of central tendency should the librarian
use?
O the mean
27, 15, 23, 15, 22, 18, 16, 14, 23, 25, 13, 29
O the median
o either the mean or median since they are the same
O neither the mean nor median because there is too
much variability
