Ogive. An Ogive (pronounced O-Jive) is a graph that represents the cumulative frequencies for the classes in a frequency distribution and it is a continuous frequency curve. Ogive has the shape of an elongated 'S' and is sometimes called a double curve with one portion being concave and the other being convex.
Cumulative Frequency is the progressive total of the frequencies. It assists us to find the median, quartiles and percentiles from large quantities of data organized into tables and graphs.To find the cumulative frequency, you add up the frequencies row by row. An Ogive is a graph of the cumulative frequency.omplete the table with two more columns for the cumulative frequency and cumulative percentage. Draw an ogive (a cumulative frequency graph). From the ogive, find the 1st quartile, median, 3rd quartile and 80th percentile.
