An ogive graph is a plot used in statistics to show cumulative frequencies. Solution: First arrange the point values in an ascending order (or descending order). So, to get from a frequency polygon to an ogive, we would add up the counts as we move from left to right in the graph. Example 1 The histogram below shows the heights (in cm) distribution of 30 people. The relative slopes from point to point will indicate greater or lesser increases; for example, a steeper slope means a greater increase than a more gradual slope. The same reasoning applies to determining the arc length K for the other two cases as well.
