# Frequency Diagrams and Polygons # Frequency Diagrams and Polygons

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.
##### Differentiated Learning Objectives
• All students should be able to plot and interpret a Frequency Diagram and Polygon for data presented in a frequency table.
• Most students should be able to plot and interpret a Frequency Diagram and Polygon for data presented in a grouped frequency table.
• Some students should be able to compare distributions using Frequency Polygons.
