Which of the following statements about data sets is true

• When the values (numbers) in a set of data are written in order, the middle value is the mean.

• The median of a set of data may or may not be a value (number) in the set.

• All sets of data have a mode.

• To find the range of a data set, always subtract the first item (number) listed from the last item (number) listed.
