An old definition for a frequency polygon is: "A distribution of discrete variates may be represented graphically by plotting the points, and drawing a broken line through them." (Kenney, 1939). This mentions the frequency polygon is used for discrete variates. However the frequency polygon is often used for grouped tables. A more modern definition is shown below.

**Construct Frequency Distribution Table And Draw Histogram**

To plot frequency polygons at GCSE students learn how to choose suitable axes depending on the categorical data and frequencies given. As learning progress they are challenged to group their own data and make comments on the trend from the frequency polygon.... To create grouped data, you need to separate the ungrouped data into different categories and then create a table that shows the relative frequency that each category occurs in the raw data

## How To Draw A Frequency Polygon For Grouped Data

Quantitative data, also called grouped data, can be displayed using a histogram or a polygon. How to graph quantitative data Put the classes on the horizontal axis.

- Draw the frequency polygon for these data using an initial class boundary of 21.5, an ending class boundary of 46.5 and 5 classes. Note that you can add or remove classes from the figure. Label each class with its midpoint.
- 13/06/2008 · Best Answer: Your data appear to be discrete, such as marks in a test out of 50. We will assume here that the data are test marks. Normally, in GCSE Maths, a frequency polygon shows the Frequency on the y-axis plotted against the Mark. Your data are grouped and so …
