I have a science prac report and according to the marking scheme, the title above is a dot point. However; i have no idea what to write for it. The errors used are predicted error, experiment error, and random error. If someone could help that would be cool.

Predicted error: Errors calculated from your results compared to literature values. (Your "percent error.")

Experiment error: Inherent errors in your experiment. No experiment is perfect. You cannot control all variables. For instance, if I measure the amount of heat inside of a foam coffee cup, my experimental error is that the foam is not a great insulator. I'm losing tons of heat that I can't measure just because of the material I'm using for the experiment.

Random error: You cannot control for these errors. They can be positive or negative. The only way to reduce random error is to take multiple data points/samples/experimental runs.
