6.00 0.66 0.57 0.62 0.62

7.00 0.76 0.72 0.67 0.72

You need to make sure that you have:

Included a heading

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
