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. While constructing, it is necessary to first have the frequency table. To plot an ogive, we need class boundaries and the cumulative frequencies. For grouped data, ogive is formed by plotting the cumulative frequency against the upper boundary of the class. For ungrouped data, cumulative frequency is plotted on the y-axis against the data which is on the x-axis.
Ogive is used to study the growth rate of data as it shows the accumulation of frequency.
