Countdown to Exams - Day 20 - Representing Data

The focus for today's snapshot is Representing data. Once data has been collected, diagrams are used to represent the data so that it is easier to extract the key points from the data without having to look at all the numbers etc. The most common diagrams that are used are Pie charts, Bar charts, Line graphs and Pictograms. It is important that you follow the rules regarding the construction of the diagrams.

In the video below, Matt will guide you through the common diagrams used to represent data and how to calculate the angles required for pie charts.
