30.4 Measures of Center
Thus far we have encountered ways to talk about how data are spread out. Another way l
investigate a data set is by selecting a numerical value in the data set that would best repie
sent a summary score. When searching for a representative score in general, statisi
often consider three values: the median, the mean, and the mode. Until now in this ciap
we have focused on the median, which is located at the middle of a data distribution.
