AssignmentGraphical presentation

You must produce a graph of your experimental data.

Your graph must:

• be a line graph or a bar graph, whichever is appropriate for your data
• be large enough to allow points to be read accurately
• have suitable scales, labels and units on the axes
• have points which are joined with a line (line graph) or clear bar tops (bar graph)

• You must use graph paper or graphing software.
• If you are using graphing software, include both major and minor gridlines, and use plotting symbols that are clear but not too large.

Data/information from an internet/literature source

• You must include data/information from an internet/literature source that you can compare with the data from your experiment.
• It must be clear from what you include that this data/information is relevant to the aim of your investigation.
• You must cite your internet/literature source within the body of the report, near to the relevant data/information, and include a reference later in the report.
• You can cite a source in many ways. One way is to put a number, for example (1), next to the data/information and the same number beside the reference included later in the report.

You must include the following information in the reference:
