You need to make sure that you have:
Included the variable symbol/unit
Used a minimum of 7 sets of data
Used the full range of measurements
Repeated each test at least 3 times
Used a suitable number of decimal places when recording results
Recorded the full precision of the measuring instrument: Instead of `1', use `1.00' if
that is what the instrument says.
Graphs
1. Include the correct label and unit on both axis
2. Choose a suitable scale
3. Graphs should cover at least half of the graph paper
4. Plot points carefully
5. Draw a line of best fit
6. When calculating the gradient, draw a triangle on your graph with sides of at least
8cm.
7. Give the gradient the correct unit.
To work out the gradient of a graph ­ y/x
