Thirty students at Eastside High School took the SAT on the same Saturday. Their raw scores are given next. (See the Excel Data File.) Consider a frequency distribution of the data that groups the data in classes of 1400 up to 1600, 1600 up to 1800, 1800 up to 2000, and so on. What graphical tool would you use to display the cumulative relative frequency of the grouped data?
A) Ogive
B) Polygon
C) Pie chart
D) Bar chart

An ogive (also known as a cumulative frequency polygon) is the best graphical tool to display the cumulative relative frequency of grouped data. It shows the cumulative percentage or proportion of data points that are below a certain value or in a certain class interval. This is appropriate for displaying cumulative relative frequency because it shows the progression of frequencies over the classes.
