Data Presentation Write-up Report

Data Presentation

 

Once you have collected your own primary data (or collated secondary data) you need to decided upon the best way to present your data in terms of tables, maps (cartographical presentations), graphs (graphical presentations) and images (your own photographs or downloads).  You must show a range of data presentation techniques.  It is important you are able to say why you selected to do each table, map or graph.  This is justification or your data presentation techniques and often gets asked about in the examination.

 

  1. A Table of your raw data – using Microsoft Excel (ICT) – highlighting unusual sites or data by shading the background of the cells.

 

  1. Base Map with annotated images of selected sites cut and pasted on.

 

  1. Base Map with proportional circles

 

  1. Isoline maps

 

  1. Kite Diagrams

 

  1. Bar Charts

 

  1. Pie Charts

 

  1. Scattergraphs

 

 

Try a complete a different method of presentation for each of your three aims.

 

You can do more than three techniques where appropriate.

 

If you try to draw a graph or chart and it is not successful – make a note of it and then suggest what element you have altered to make it more successful.  Evaluating what has not gone so well and suggesting changes is all part of the justification process.

Data Presentation Techniques

 

Deciding on the most appropriate data presentation techniques for the values have collected is very important.  For example, line graphs should only ever be used for continuous data, such as temperature recordings, so if you do not have temperature data, do not use a line graph!  If you have data on vegetation abundance, kite diagrams are usually appropriate.

 

To help you choose the correct data presentation techniques start by reading ‘Lenon and Cleves’ and ‘St. John and Richardson’.
