Graphical presentation
You must produce a graph of your experimental results.
The graph must:
- be a scatter graph, 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.
You must use graph paper or graphing software.
If you are using graphing software, you must include both major and minor gridlines. You must use plotting symbols that are clear but not too large.
If you are plotting a scatter graph, a line or curve of best fit should usually be drawn.
