Drawing Graphs
Plotting Data
Plotting data allows you to see any trends or patterns in your results:
-
Make sure your graph is large enough
-
Look at your data and choose a sensible scale
-
Take care to plot your points accurately
Lines of Best Fit
A line of best fit should be drawn, passing as close to as many data points as possible:
-
Straight lines should be drawn with a ruler
-
Sometimes a curved line is more appropriate and this can be drawn freehand
Anomalous Results
An anomalous result does not fit the pattern:
-
Plot all your data on your graph
-
If you have any anomalies, ignore them when drawing your line of best fit
