A graph of a cumulative frequency distribution is called **Ogive.**

Ogive: In statistics, an ogive, also known as a **cumulative frequency polygon**, can refer to one of two things:

- any
**hand-drawn graphic**of a cumulative distribution function - any
**empirical**cumulative distribution function.

The points plotted as part of an ogive are the upper-class limit and the corresponding cumulative absolute frequency or cumulative relative frequency. The ogive for the normal distribution resembles one side of an **Arabesque or ogival arch**, which is likely the origin of its name.

**1. Frequency Polygon**: A frequency polygon is a graph constructed by using lines to join the midpoints of each interval or bin. The heights of the points represent the frequencies. A frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table.

**2. Frequency Curve**: A Frequency Curve is a smooth curve which corresponds to the limiting case of a histogram computed for a frequency distribution of a continuous distribution as the number of data points becomes very large.

**3. Pie Diagram**: A pie diagram is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice is proportional to the quantity it represents.

**Thus, option 3 is the correct answer.**
