Graphs and Charts

Why use graphs and charts?. Presenting data in graphs and charts helps us to see patterns in the data more clearly. When we present data in this way we might see things that we might not have seen when just looking at the set of raw figures.It helps us to show those patterns to others too.Certain types of chart help us to explore links between sets of data which is great for investigations

    1. Graphs and Charts Ways of presenting geographical data

    2. Why use graphs and charts? Presenting data in graphs and charts helps us to see patterns in the data more clearly. When we present data in this way we might see things that we might not have seen when just looking at the set of raw figures. It helps us to show those patterns to others too. Certain types of chart help us to explore links between sets of data which is great for investigations……

    3. Pie Charts

    4. Pie Charts Become Doughnuts Use Excel to turn pie charts into ring or doughnut charts….

    5. Bar Charts Keep the bars on charts separate unless showing continuous data

    6. Line Graph Brilliant for showing changes in the same thing over time

    7. Composite Line Graph You can use this to show different sets of information and compare them - a more complex way of showing data

    8. Cluster Bar Charts These are great for showing sets of the same type of data collected at different time periods.

    9. More examples of bar charts….

    10. Composite Bar Charts Great for when a total figure is made up of different sets of figures

    11. This bar chart allows you to show negative data… This chart allows you to chow negative data and could be used if you have had a score system with a negative scale

    12. Proportional Arrows

    13. Proportional circles (Can be proportional semi-circles if showing two sets of data)

    14. Proportional Circles Combined With Pie Charts

    15. Rose Diagram

    16. Radar Graph (aka Star Chart) Super for showing scores for different criteria. You can build up several different lines on the same graph either directly on the one piece of paper, or on overlays.

    17. Radar Graph 2

    18. Scatter Graphs Useful for helping you to see if there is a relationship (correlation) between two sets of information.. You can see of one figure changes if there is a corresponding reaction in the other figure)

    19. Scatter Graph With A Difference! This chart shows that more people prefer hamburgers with between 2 an 10% non meat filler and between 38% and 65% fat. The least number of people prefer bugers with around 17% non meat filler and 60% fat.

    20. A Kite Chart

    21. Flow Charts These help you to show cause and effect…great for developing explanations and organising your thoughts….

    22. Spidergrams Useful for just about anything, especially for information that cannot be displayed graphically…

    23. What else? You can combine some of the above methods with maps. For example, you can put a bar to show a total figure, at a place where the information shown in that bar was collected. You could add on other bars from other sets of data for comparison… What other charts can be combined with maps?

    24. Dot Maps

    25. Chloropleth Maps – use different shades of the same colour

    26. Photos Photos are great and can be used to back up some of the data that you have shown in your charts and graphs as well as real images…

    27. Tape recordings and videos Give atmosphere and bring a study to life…

    28. Getting Help http//:www.teachingideas.co.uk The website above is really helpful, but any internet search such as – how do I draw a chloropleth map? – will help too Check put the books in the department Ask your teacher
