Graphs in CIE IGCSE Biology Alternative to Practical

Do a line through most points. If one is quite far out, the next question is likely to ask if there is an anomalous result (one which is unexpected; doesn;t fit into the results). If it is a curve, don't use a ruler. Make sure the correlation is shown through the line. Good luck!

Thanks

Make sure you draw a line through all the points except the ones which are anomalous and never use a ruler unless the points line up exactly
