Confronted with quantities of numbers it is difficult to make sense. Graphs and charts when used properly quickly allow us to understand the significance of our data samples.
Prior Knowledge & Skills
Understanding numbers, basic 2D shapes, and 2D coordinates help us to create graphs and charts.
Usually beginning with bar charts we progress to line graphs and pie charts. We can adopt the use of technology to help us with the drawing of these diagrams. Moving on to scatter graphs and statistical diagrams like box plots. There are many parallels in different areas of maths using graphs including algebra, shape and position, and number.
Graphs and charts are used universally to present an efficient visualisation of data. Whether in office presentations to justify a point or in the press to emphasise the main theme of a story.
