9. For an ordered numerical data set, quartiles are the three numbers that divide the data set into quarters.
10. A graphical representation of a numerical data set that has been grouped into intervals.
11. The extent to which data values in a data set differ from each other.
12. A question that can be answered by collecting data values that can vary
14. The middle number of an ordered set of values
