**Frequency Polygon**. A

**frequency polygon**is a graphical form of representation of data. It is used to depict the shape of the data and to depict trends. It is usually drawn with the help of a histogram but can be drawn without it as well.

Correspondingly, what is frequency polygon with example?

**Frequency** polygons are a graphical device for understanding the shapes of distributions. They serve the same purpose as histograms, but are especially helpful for comparing sets of data. **Frequency** polygons are also a good choice for displaying cumulative **frequency** distributions.

Also Know, what are the characteristics of frequency polygon? A frequency polygon is very similar to a histogram. In fact, they are almost identical except that frequency polygons can be used to compare sets of data or to display a cumulative frequency **distribution**. In addition, histograms tend to be rectangles while a frequency polygon resembles a line graph.

Accordingly, what is 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**.

How do you construct a frequency table?

**To construct a frequency table, we proceed as follows:**

- Construct a table with three columns. The first column shows what is being arranged in ascending order (i.e. the marks).
- Go through the list of marks.
- Count the number of tally marks for each mark and write it in third column.
