How to Draw Frequency Polygon?
Following the procedures listed below, construct a histogram before beginning to draw frequency polygons:
- Step 1: First, select the class interval and then indicate the values on the axes.
- Step 2: Label the horizontal axes with the midpoint of each interval.
- Step 3: Label the vertical axes with the class frequency.
- Step 4: Mark a point at the height in the centre of each class interval according to the frequency of each class interval.
- Step 5: Use the line segment to join these spots.
- Step 6: The representation that was obtained is a frequency polygon.

Frequency Polygons in Statistics
Frequency Polygons in Statistics: A frequency polygon is a type of line graph where the frequencies of classes are plotted against their midpoints. This graphical representation closely resembles a histogram and is typically used for comparing data sets or showing cumulative frequency distributions. It uses a line graph to represent quantitative data.
Frequency polygons are one of the great methods to represent statistical data so that it can be read easily. In statistics, we deal with lots of data, and reading it quickly is necessary for solving statistical problems effectively.
Frequency polygons help us to achieve the same result. In this article, we will learn about frequency polygons, their formula, examples, and others in detail.
