Learn moreFrequency polygon

A frequency polygon is a line graph, and it is obtained by

**.****joining the mid-points of the frequency rectangles****Let us look at an example of a frequency polygon**.

The line graph forms a closed surface with many sides, hence the name frequency 'polygon'.

Types of frequency polygon

Frequency polygons are of two types, namely:

**1.**Frequency polygon with histogram

**2.**Frequency polygon without histogram.

When the line graph is over a histogram, then it is a frequency polygon with a histogram.

When the line graph alone is visible while the histogram is not, it is a frequency polygon without a histogram.
