An ogive (also known as a cumulative frequency polygon) is the best choice to display the cumulative relative frequency of the grouped data. An ogive displays the cumulative frequencies of each class as points plotted on a graph, and then connects these points with lines to create a smooth curve. This allows us to easily see how many students scored at or below a certain score range.
