Frequency Polygon Graph
Frequency Polygon Graph is the graphical representation of the data given in the form of class interval and frequency. Let’s consider an example for better understanding:
Example: Plot the graph of the Frequency Polygon for the following data which represents the number of goals scored in a match in a league throughout the season:
Goals Scored | Frequency |
---|---|
0 |
3 |
1 |
7 |
2 |
8 |
3 |
12 |
4 |
2 |
5 |
5 |
Answer:
For the given data, we can plot the frequency polygon by representing the goals scored on the vertical axis and frequency on the horizontal axis, as follows:
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.
